Ed Miliband is now more likely than David Cameron to be prime minister after the election, according to new bookies’ odds.

The bookmakers’ PaddyPower now has Ed Miliband at 5/6 odds, with David Cameron trailing behind on 10/11.

Despite the Tories failing to open up a sustained lead against Labour, Mr Miliband’s low personal ratings have convinced many watchers that Labour will not win the election.

Labour’s poll ratings have been in front of the Conservatives’ for the vast majority of this parliament, with the two parties now broadly neck-and-neck.

Mr Miliband has also seen a steady uptick in his personal scores since the start of the official campaign season.

With this in mind, this is the first time during the campaign that Mr Miliband has been seen as the most likely victor after the election.

The bookies also have Mayor of London Boris Johnson in third place at 35/1.

Cameron is making no headway and refusing the debate was a misjudgement. Even if the Conservatives are the largest party I cannot see how they can win enough seats to form a viable alternative to an Ed-led, three-way arrangement with the Lib Dems and SNP.” Andrew Hawkins In pictures: Experts' predictions for the General Election - 19/04/15 Joe Twyman (YouGov) “Ed Miliband’s performance at the challengers’ debate could boost his ratings, and may result in a short-term boost for his party’s fortune, but I think it unlikely to change the overall picture longer term.” In pictures: Experts' predictions for the General Election - 19/04/15 Ben Page (Ipsos MORI) “Labour had the better week, and Ed Miliband is improving his personal ratings from a low base, but neither of the two main parties is getting a majority in these numbers.” In pictures: Experts' predictions for the General Election - 19/04/15 Rick Nye (Populus) “Still no change.” In pictures: Experts' predictions for the General Election - 19/04/15 Nick Moon (GfK) “I agree with Rick [Nye, who said “no change” last week]. Most campaigns don’t really see much change.” In pictures: Experts' predictions for the General Election - 19/04/15 Damian Lyons Lowe (Survation) “On the balance of Thursday’s debate – I’m staying unchanged.” In pictures: Experts' predictions for the General Election - 19/04/15 Michelle Harrison (TNS) “The Conservatives and Labour have barely moved. The most notable event? The SNP hitting 52 per cent on the latest TNS Scotland poll. A key theme for this election is the impact of ‘edge’ politics on the centre.” In pictures: Experts' predictions for the General Election - 19/04/15 James Endersby (Opinium Research) “Our poll gives the Tories a four-point lead. It was carried out either side of Thursday’s TV debate so we haven’t seen the expected dent in Tory fortunes yet. The pattern we’ve seen for a while now appears to be unaffected by week-to-week events. If our figures hold fast, the Lib Dems would still be kingmakers as Tories plus DUP wouldn’t equal 326 seats, but neither would SNP plus Labour. Both sides would need the Lib Dems to eke out a majority.” In pictures: Experts' predictions for the General Election - 19/04/15 Martin Boon (ICM) “We caused something of a kerfuffle this week with a Tory six-pointer. Looking back over the last four campaigns, on each occasion the incumbent government just failed to reach the vote share achieved on our first campaign poll. As I’m reaching for an answer, on that basis alone I’ll go for 36 per cent for the Tories and 34 per cent for Labour.” In pictures: Experts' predictions for the General Election - 19/04/15 Lord Ashcroft (Lord Ashcroft Polls) He refuses to make predictions. “My polls are snapshots, not predictions.” Rex

Mr Johnson is standing as an MP at the election and in theory could become leader before a government was formed if David Cameron were to resign.

The latest poll is a Guardian/ICM survey showing the Conservatives with a narrow lead over Labour by 34% to 32%. The Liberal Democrats at on 10%, Ukip on 11% and the Green Party on 5%.

The SNP are likely to gain a large proportion of Scotland’s seats if local polling in Scotland is replicated on polling day.
