• Ed Miliband said banks would be encouraged to fund 125,000 new homes for first-time buyers in England under a Labour government
• The Lib Dems set out plans for a £2.5bn healthcare fund to alleviate pressure on hospitals in England

An average of a dozen campaign polls so far suggests the Conservatives are on 34%, three points down on their vote share in May 2010 – an election they lost; Labour also on a 34% average, some four points up on their dire 2010 performance; the Lib Dems on an average of 8% - one-third of the support they received in 2010; UKIP’s average was 14% (up 11 points on 2010) and the Greens were on 5% (up 4 points). How these dozen individual poll results play out in 650 individual constituency contests on 7 May will doubtless be a joy to behold; but until then we mere mortals have to make what we can of the evidence. At present it appears like the finish of the 10,000 metres, where no-one has the momentum to break from the pack and everyone is bunched, waiting for the bell signalling the final lap.

Sunday Times political editor Tim Shipman has shared on Twitter, external some of the political tidbits to be found within the paper tomorrow. Among them:

• Nigel Farage says six Tory MPs will defect to UKIP if David Cameron tries to enter into coalition with the Lib Dems - especially if it gives Nick Clegg "control of the referendum question"

• Paul Nuttall, UKIP deputy leader, and Suzanne Evans, UKIP deputy chairman, are Mr Farage's preferred successors if he loses in Thanet South and resigns the party leadership
• Vince Cable is being urged by senior Lib Dems to become a caretaker leader and take the party into coalition
• Shadow education secretary Tristram Hunt says Labour will make sure every headteacher has a leadership qualification
• And Nicola Sturgeon and Leanne Wood are set to co-ordinate an assault on Ed Miliband in the upcoming "challengers' debate" on the BBC

The paper's main story is the result of a poll which finds that the Conservatives are trusted to get a better deal for workers in large companies, while Labour have the edge in helping workers in smaller firms.

Osborne plans 'housing revolution'

The Sunday Telegraph has an interview with Chancellor George Osborne, external, who is outlining plans for a "1980s-style housing revolution". Mr Osborne tells the paper one million home-buyers will be given direct government assistance - but that in an early Budget in the next parliament he would propose measures aiming to double that number of new buyers by 2020.

Tomorrow's Observer carries an article by Scottish First Minister Nicola Sturgeon, external, in which the SNP leader offers to "help make Ed Miliband the next prime minister". It comes in the aftermath of allegations - which she strongly denies - that Ms Sturgeon said David Cameron was a preferable prime minister to the Labour leader. In tomorrow's article, she repeats that she said no such thing, and extends an offering to Mr Miliband: “If together our parties have the parliamentary numbers required after 7 May, and regardless of which is the biggest party, will he and Labour join with us in locking David Cameron out of Downing Street?”

At the New Statesman, Ian Leslie wonders, external if David Cameron's "oddly recessive" performance in the debates shows that the prime minister has lost his desire for the job: "On that night and during the debate, Cameron has performed like an animatronic, lacking in animus. It’s sad to see. Most of us have been in jobs where we end up just going through the motions, and it doesn’t feel good."

What an extraordinary level of vicious abuse I have received today for simply reporting the news. Is this the country we want folks? Is it?

OF COURSE there are some SNP strategists - I know, I've spoken to them - who say in private a Tory victory would hasten independence.

OF COURSE I won't identify the SNP folk who said to me in private conversations that they could see the attraction/would prefer Tory govt.

OF COURSE I should ask tough questions of politicians. This is a democracy. This is my role in it. We're the poorer without challenge.
