Do the bishops in the House of Lords actually change anything?

When 0.8 of a bishop turns up to each vote (on average), it's hard to argue they have a substantial effect.

In the wake of the Church of England's vote to continue banning women from being bishops, there have been renewed calls to remove bishops from the House of Lords. This e-petition, for instance, argues that:

The Church of England on 20th Nov 2012 voted not to allow women to be Bishops. Though that is within its rights to do, this should worry the Government as Church of England Bishops are awarded legislative power through seats in the House of Lords.

The Church has chosen to be a sexist organisation by refusing women the right to hold highest leadership positions and therefore should not be allowed automatic seats in the House of Lords, as this clearly does not comply with the spirit of UK Equality law.

But does it actually matter that bishops are in the House of Lords? Clearly, I'm not talking about points of principle; having a religious organisation in the House of Lords is as symbolically wrong as having a hereditary monarch as the head of state. It represents a Britain which hasn't existed for a very long time, and actively denigrates many people's conception of their own nationality.

But do the bishops in the Lords actually affect anything? A 2007 paper from UCL's Meg Russell and Maria Sciara, titled "Why Does the Government get Defeated in the House of Lords?: The Lords, the Party System and British Politics" suggests not.

There are 26 bishops seats in the house of lords (although that number varies occasionally due to deaths and retirements, and currently only 25 are present). That is out of 760 seats overall, and compares to the 212 Conservative, 225 Labour, and 90 Liberal Democrat peers. In other words, if turnout were 100 per cent, and party lines held all the time, the bishops would never matter – the vote would go to the coalition every time.

The first snag are the crossbenchers – 176 peers who aren't affiliated with any parties. But even they don't affect the outcome all that often. Of all 806 whipped votes in the Lords between 1999 and 2005, the crossbenchers changed the outcome just 50 times. That is, if they had not voted, 37 defeats would have been turned to victory, ten defeats would have been turned to a draw, two victories would have been turned to a draw, and one draw would have been turned to a victory.

The second snag, and the one the parties battle with most frequently, is turnout. In the same period, the mean turnout for Labour and Liberal Democrat peers was just over 50 per cent, and while it was just 34 per cent for the Tories. For the parties, boosting turnout is by far the most important way to win votes. Once the whipped lords actually turned up, they tended to vote with their party, with 97 to 99 per cent cohesiveness.

In this sleepy chamber, where do the bishops fit in? The authors write:

The Bishops’ impact… is limited by the fact that they are a small group, and that like the Crossbenchers they vote relatively little, and do not vote as a cohesive block.

Most of the time, there is only one bishop at each vote (they actually have a formal rota, apparently), and their mean turnout is just 3.2 per cent. As in, four-fifths of a person. Only ten times in six years were there votes with more than five bishops attending (only 66 times with more than one):

The largest turnouts were 11 votes on the balloting of grammar schools in 2000 (when nine Bishops supported the government and two opposed), on the Civil Partnerships Bill in 2004 (eight supporting, two opposed), and on the Learning and Skills Bill in 2000 with respect to sex education guidelines to replace Section 28.19.

So there aren't many bishops in the lords, and they rarely turn up. Which is why it's not a surprise that, over 806 divisions and six years, only three times did the bishops make a difference. Twice, the government was defeated by one vote when the sole bishop voted against it, and once the government was defeated by one vote when three bishops voted against it:

This was over the issue of education of asylum seekers’ children, where an amendment moved by the Bishop of Portsmouth required that such children are taught in a school and not separately in a detention centre. Three Bishops attended and voted against the government, and it lost the division by one vote.

When it comes to the simple legislative arithmetic, it is largely irrelevant whether we have bishops in the lords. A dodgy batch of mussels in the House of Lords' restaurant would probably have a greater material effect on the outcome of divisions that the lords spiritual do.

There are, of course, benefits for the bishops which are harder to quantify. Being peers gives them the ability to lobby others more effectively; and there were almost certainly times when the threat of defeat caused the government to change its legislative program pre-emptively.

Nonetheless, those fighting to remove Bishops from the Lords are doing the right thing by focusing on matters of principle, such as equality and secularity. When it comes to substance, there really isn't a whole lot to object to.

Who'll win the Richmond Park by-election?

There are three known unknowns that will decide the contest. 

It’s official: Zac Goldsmith has resigned as the Conservative MP for his Richmond Park seat, and has triggered a by-election there, where he will stand as an independent candidate.

Will it be a two-way or a three-way race?

The big question is whether the contest will be a three way fight between him, the Liberal Democrat candidate Sarah Olney, and an official Conservative candidate, or if CCHQ will decide to write the thing off and not field a candidate, making it a two-horse race between Goldsmith and Olney.

There are several Tory MPs who are of the opinion that, given that latitude to disagree on Heathrow has been granted to two Cabinet ministers, Boris Johnson and Justine Greening, similar leeway should be extended to Goldsmith. It’s win-win for Downing Street not to contest it, partly because doing so would put anti-Heathrow MPs, including Johnson and Greening, in an impossible position. Theresa May isn’t averse to putting Johnson in a tricky spot, but Greening was an early supporter of her leadership bid, so her interests come fairly high up the prime ministerial radar.

But the second reason not to contest it is that Goldsmith’s chances of re-election will be put in a serious jeopardy if there is a Tory candidate in the race. Everything from the local elections in May or the Liberal mini-revival since Brexit indicates that in a three-way race, they will start as heavy favourites, and if a three-way race results in a Liberal Democrat win there will be bloodletting.

Although people are talking up Goldsmith’s personal vote, I can find little hard evidence that he has one worth writing home about. His performance in the wards of Richmond Park in the mayoral election was actually a bit worse than the overall Tory performance in London.  (Boris Johnson didn’t have a London seat so we cannot compare like-for-like, but Sadiq Khan did four points better in Tooting than he did across London and significantly outperformed his general election performance there.) He did get a big swing from Liberal to Conservative at the general election, but big swings from the Liberal candidate to the Tory were a general feature of the night, and I’m not wholly convinced, given his performance in Richmond Park in 2016, that it can be laid at Goldsmith’s door.

If he wins, it’ll be because he was the Conservative candidate, rather than through any particular affection for him personally.

But will being the Conservative candidate be enough?

Although on paper, he inherits a healthy majority. So did Robert Courts, the new MP for Witney, and he saw it fall by 19 points, with the Liberal Democrats storming from fourth to second place. Although Goldsmith could, just about, survive a fall of that magnitude, there are reasons to believe it may be worse in Richmond Park than Witney.

The first is that we already know, not just from Witney but from local council by-elections, that the Liberal Democrats can hurt the Conservatives in affluent areas that backed a Remain vote. But in Witney, they barely squeezed the Labour vote, which went down by just over two points, or the Green vote, which went down by just under two points. If in Richmond Park, they can both damage the Tory vote thanks to Brexit and squeeze Labour and the Greens, they will win.

Goldsmith's dog-whistle campaign for the London mayoralty will particularly help squeeze the Labour vote, and thanks to Witney, the Liberal Democrats have a ready-made squeeze message. (In Witney, Green and Labour votes would have been more than enough to elect Liz Leffman, the Liberal candidate.)

But their good performance in Witney and Goldsmith's mayoral result may not be enough on their own.  Ultimately, the contest will come down to the big question that will decide not just the outcome in Richmond Park but the future of the Liberal Democrats.

Have the voters forgiven the Liberal Democrats for going into coalition?

We know that Brexit can help the Liberal Democrats at the direct expense of the Conservatives. What we don’t know is if Brexit is enough to convince 6,000 Labour voters in Bath to vote tactically to get Ben Howlett out in exchange for a Lib Dem, or for 7,500 Labour voters to back a Liberal candidate in Hazel Grove to defeat William Wragg.

One of the reasons why the Liberal Democrats lost votes directly to the Tories in 2015 was fear: of uncertainty and chaos under an Ed Miliband government propped up by the SNP. That factor is less live in a by-election but has been further weakened due to the fact that Brexit – at least as far as Remain-backing Conservatives are concerned – has brought just as much uncertainty and chaos as Miliband and the SNP ever would have.

But the other reason was disgust at the Liberal Democrats for going into coalition with the Conservatives. If they can’t win over enough votes from the parties of the left, we’ll know that the party still has a way to come before we can truly speak of a Liberal revival.
