Eastleigh is now even more of a must-win for the Tories

The Huhne and Rennard scandals mean defeat will be portrayed as a humiliating set-back for Cameron.

Last week the Tories were increasingly resigned to defeat in the Eastleigh by-election but the Rennard allegations, combined with a poll (conducted before the story broke) putting them four points ahead of the Lib Dems, have given the party renewed hope of winning the seat. The odds on a Lib Dem victory have lengthened, while those on a Conservative victory have narrowed. 

My sense, however, is that the Rennard story, like the Huhne scandal, will have little effect on the outcome. As one Lib Dem tells the Times today, "If Chris Huhne lying isn’t going to derail us then a peer that very few people have heard of is not going to harm us". Nick Clegg was almost certainly right when he suggested this morning that local issues such as planning would continue to dominate. 

But this doesn't alter the fact that Eastleigh is now even more of a must-win seat for the Tories. The Huhne and Rennard scandals, notwithstanding their limited influence on voters, give the press every excuse they need to portray any defeat as a humiliating set-back for Cameron. In such circumstances, the only consolation for the Tories will be that Labour, which is set to finish in fourth place behind UKIP, will face some tough questions of its own.

No one ever expected Labour, which polled just nine per cent in Eastleigh at the general election, to win the seat. The swing required would put the party on course for a majority of 362. But as the only large opposition party, not least one which claims to be a "one nation" force, it should be performing much better midway through the parliament.

Why are boundary changes bad for Labour?

New boundaries, a smaller House of Commons and the shift to individual electoral registration all tilt the electoral battlefield further towards the Conservatives. Why?

The government has confirmed it will push ahead with plans to reduce the House of Commons to 600 seats from 650.  Why is that such bad news for the Labour Party? 

The damage is twofold. The switch to individual electoral registration will hurt Labour more than its rivals. . Constituency boundaries in Britain are drawn on registered electors, not by population - the average seat has around 70,000 voters but a population of 90,000, although there are significant variations within that. On the whole, at present, Labour MPs tend to have seats with fewer voters than their Conservative counterparts. These changes were halted by the Liberal Democrats in the coalition years but are now back on course.

The new, 600-member constituencies will all but eliminate those variations on mainland Britain, although the Isle of Wight, and the Scottish island constituencies will remain special cases. The net effect will be to reduce the number of Labour seats - and to make the remaining seats more marginal. (Of the 50 seats that would have been eradicated had the 2013 review taken place, 35 were held by Labour, including deputy leader Tom Watson's seat of West Bromwich East.)

Why will Labour seats become more marginal? For the most part, as seats expand, they will take on increasing numbers of suburban and rural voters, who tend to vote Conservative. The city of Leicester is a good example: currently the city sends three Labour MPs to Westminster, each with large majorities. Under boundary changes, all three could become more marginal as they take on more wards from the surrounding county. Liz Kendall's Leicester West seat is likely to have a particularly large influx of Tory voters, turning the seat - a Labour stronghold since 1945 - into a marginal. 

The pattern is fairly consistent throughout the United Kingdom - Labour safe seats either vanishing or becoming marginal or even Tory seats. On Merseyside, three seats - Frank Field's Birkenhead, a Labour seat since 1950, and two marginal Labour held seats, Wirral South and Wirral West - will become two: a safe Labour seat, and a safe Conservative seat on the Wirral. Lillian Greenwood, the Shadow Transport Secretary, would see her Nottingham seat take more of the Nottinghamshire countryside, becoming a Conservative-held marginal. 

The traffic - at least in the 2013 review - was not entirely one-way. Jane Ellison, the Tory MP for Battersea, would find herself fighting a seat with a notional Labour majority of just under 3,000, as opposed to her current majority of close to 8,000. 

But the net effect of the boundary review and the shrinking of the size of the House of Commons would be to the advantage of the Conservatives. If the 2015 election had been held using the 2013 boundaries, the Tories would have a majority of 22 – and Labour would have just 216 seats against 232 now.

It may be, however, that Labour dodges a bullet – because while the boundary changes would have given the Conservatives a bigger majority, they would have significantly fewer MPs – down to 311 from 330, a loss of 19 members of Parliament. Although the whips are attempting to steady the nerves of backbenchers about the potential loss of their seats, that the number of Conservative MPs who face involuntary retirement due to boundary changes is bigger than the party’s parliamentary majority may force a U-Turn.

That said, Labour’s relatively weak electoral showing may calm jittery Tory MPs. Two months into Ed Miliband’s leadership, Labour averaged 39 per cent in the polls. They got 31 per cent of the vote in 2015. Two months into Tony Blair’s leadership, Labour were on 53 per cent of the vote. They got 43 per cent of the vote. A month and a half into Jeremy Corbyn’s leadership, Labour is on 31 per cent of the vote.  A Blair-style drop of ten points would see the Tories net 388 seats under the new boundaries, with Labour on 131. A smaller Miliband-style drop would give the Conservatives 364, and leave Labour with 153 MPs.  

On Labour’s current trajectory, Tory MPs who lose out due to boundary changes may feel comfortable in their chances of picking up a seat elsewhere.
