Would a new Lib Dem leader help the Tories win in 2015?

Why some Tories believe that the replacement of Clegg with Vince Cable or Tim Farron is essential to their election chances.

One of the reasons why some Conservatives believe it will be impossible for David Cameron to win a majority at the next election is the scale of the defection of Liberal Democrat supporters to Labour. If Ed Miliband's party hangs on to around a third of the Lib Dems' 2010 voters, the Tories stand to lose dozens of seats at the next election - there are 37 Conservative-Labour marginals where the third place Lib Dem vote is more than twice the margin of victory. In the 1980s, it was the formation of the Social Democratic Party and the resultant split in the centre-left vote that allowed Margaret Thatcher to win successive landslide victories. In 2015, the collapse in support for the Liberal Democrats and the reunification of the left around Labour could bring Miliband to power.

This fact has led some Conservatives to wonder aloud whether a change of Liberal Democrat leader before 2015 is now in their interests. The hope is that a more left-wing leader such as Vince Cable or Tim Farron, both of whom have signalled their availability, could prompt the party's former supporters to return home from Labour. ConservativeHome editor Tim Montgomerie recently told me that "a left-wing replacement" of Nick Clegg in 2014 was "vital to Tory hopes".

Those with an interest in a Lib Dem recovery have been encouraged by polls showing that the party would perform better with Cable as leader. A ComRes survey last September showed that support for the Lib Dems would rise to 18 per cent under Cable, compared to 14 per cent under Clegg. However, it is doubtful whether this bounce would last once Cable was forced to take responsibility for all coalition decisions (something he has skillfully avoided doing to date. Few would know, for instance, that it was Cable's department that introduced higher tuition fees) It is also the case that the party's former left-wing supporters, those who defected from Labour over Iraq and top-up fees, are likely to prove the hardest to win back.

But as we get closer to the election, this discussion will be had with increasing frequency in Lib Dem and Tory circles. If the Lib Dems are still flatlining at 10 per cent in the polls in 2014, it is hard to see the party not taking a gamble on an alternative leader. The dilemma for the Tories is whether to help shore up Clegg's position, for the sake of coalition unity, or to tacitly encourage a revolt against him.

Who will win in Manchester Gorton?

Will Labour lose in Manchester Gorton?

The death of Gerald Kaufman will trigger a by-election in his Manchester Gorton seat, which has been Labour-held since 1935.

Coming so soon after the disappointing results in Copeland – where the seat was lost to the Tories – and Stoke – where the party lost vote share – some overly excitable commentators are talking up the possibility of an upset in the Manchester seat.

But Gorton is very different to Stoke-on-Trent and to Copeland. The Labour lead is 56 points, compared to 16.5 points in Stoke-on-Trent and 6.5 points in Copeland. (As I’ve written before and will doubtless write again, it’s much more instructive to talk about vote share rather than vote numbers in British elections. Most of the country tends to vote in the same way even if they vote at different volumes.)

That 47 per cent of the seat's residents come from a non-white background and that the Labour party holds every council seat in the constituency only adds to the party's strong position here. 

But that doesn’t mean that there is no interest to be had in the contest at all. That the seat voted heavily to remain in the European Union – around 65 per cent according to Chris Hanretty’s estimates – will provide a glimmer of hope to the Liberal Democrats that they can finish a strong second, as they did consistently from 1992 to 2010, before slumping to fifth in 2015.

How they do in second place will inform how jittery Labour MPs with smaller majorities and a history of Liberal Democrat activity are about Labour’s embrace of Brexit.

They also have a narrow chance of becoming competitive should Labour’s selection turn acrimonious. The seat has been in special measures since 2004, which means the selection will be run by the party’s national executive committee, though several local candidates are tipped to run, with Afzal Khan,  a local MEP, and Julie Reid, a local councillor, both expected to run for the vacant seats.

It’s highly unlikely but if the selection occurs in a way that irritates the local party or provokes serious local in-fighting, you can just about see how the Liberal Democrats give everyone a surprise. But it’s about as likely as the United States men landing on Mars any time soon – plausible, but far-fetched.
