Tax has been the main talking point.

* The Conservatives claim 94% of working households are better off under the coalition's tax and benefit changes, while Labour argues families are on average £1,100 a year worse off than in 2010.

* The Lib Dems and Conservatives battled to claim the credit for increasing the starting point at which people pay income tax.

* Former Conservative candidate for Hull West and Hessle, Mike Whitehead, has joined UKIP. Nigel Farage claimed it was a "defection", while the Conservatives say he was sacked.

* The Green Party replaced its candidate for Erewash after Victoria Martindale, who was serving a suspended jail sentence for breaching gas safety regulations at a property she was letting out, stepped down.

With Tuesday's Guardian and the Independent both reporting former Labour PM Tony Blair is to enter the election fray with an attack on the Conservatives' over Europe, the Conservatives have this evening issued a statement:

Martin Bentham, of London's Evening Standard, tells the BBC News Channel that Mr Cameron's appeal - as highlighted by the Telegraph, external - is symptomatic of the main parties trying to harden up their core vote.

The Telegraph's front page - featuring David Cameron's call for UKIP voters to "come home" to the Conservative Party - is interesting the BBC News Channel's paper reviewers.

Gaurdian diarist Hugh Muir reminds viewers that it's often said about David Cameron that he's much better on tactics than strategy, adding:

The Guardian has advance notice that former Prime Minister Tony Blair is to "step into the election battle" by giving a speech warning of the "chaos" that could be caused by a vote to leave the EU, should the Conservatives win a majority on 7 May.

"Think of the chaos produced by the possibility, never mind the reality, of Britain quitting Europe," he will reportedly say. "Jobs that are secure suddenly insecure; investment decisions postponed or cancelled; a pall of unpredictability hanging over the British economy."

The former PM praises Labour leader Ed Miliband for showing real leadership on the issue by following his own convictions "even when they go against the tide”.

The papers are starting to release images of Tuesday's front pages. And the FT has grim news for the next government, saying whoever wins the election will face an "immediate crisis" in the NHS budget. Finances are, apparently, in a much worse state than thought.

"Woking My Way Back To You", "Arundel All Night" and "I Fought Bassetlaw" were my feeble attempts to join the Twitter meme du jour, where social media users have been contributing their own suggestions under the hashtag #constituencysongs. We've rounded up some of them here .

In a contest widely described as the UK's first digital general election (although your correspondent remembers such a title being pinned to the 2010 vote), a new study suggests Prime Minister David Cameron has beaten comedian Russell Brand to the title of Britain's "most politically influential person on social media".

The study by social media consultancy Telegraph Hill puts London mayor and prospective Tory candidate Boris Johnson third in a study of 800 politicians and commentators.

Labour leader Ed Miliband was fourth, while SNP leader Nicola Sturgeon was in fifth place.

Our correspondent says the parties will spend the coming weeks arguing over those voters who remain undecided. "There will be quite a lot of those people. Opinions vary but it's thought that maybe 24% - nearly one-in-four haven't decided which way they're going to jump," he adds.

David Cameron said there was not just an economic case but a moral case for low taxes, adding this went to the heart of what he believed in as a Conservative.

But in an apparent acknowledgement that many people do not yet feel they are benefitting from the upturn in the economy, he said: "I don't just want people to see Britain's recovery on the TV or hear it on the radio, I want them to feel it in their lives."

He claimed today's changes would help that to happen.

There is another flipside to the commitment to low taxes. The Tories need to save £30bn to eliminate the deficit by 2017-18 and if they won't put up taxes, all the money will have to come from spending cuts.

They have said they will save £5bn by cracking down on tax avoidance, £13bn from departmental spending and £12bn from welfare.

But there remain big unanswered questions on which benefits and which government projects will have to be axed.

Labour faces similar questions about which taxes it would increase and what public spending it would cut to meet its commitment to eliminating the deficit as soon as possible in the next parliament.

Conservative leader David Cameron has urged potential UKIP voters to "come home" to the Tories on 7 May, but his appeal has been rejected by the anti-EU party's leader, Nigel Farage:

If some, despairing at the "flatness" of the campaign so far, hope for more visionary policies, Financial Times writer Janan Ganesh reckons they're misguided, external . He writes "swing voters worry about the Tories' blueprint for a smaller state and Labour's taste for leveraged spending... their grievance with the main parties is actually their excess of vision not their lack of it".

"The average voter is indifferent to politics," he says, arguing that it's a good thing.

Proof the Lib Dems can organise a good booze-up: Leader Nick Clegg ensures he's got the right pump before pouring a pint of Somerset-brewed Butcombe Bitter at the Green Park brasserie, Bath. The deputy PM reportedly declared the beer to be "very nice".

The PM is asked if he regrets expressing scepticism about the plan to raise the income tax threshold when it was put forward by the Lib Dems. "This tax cut has been delivered by a Conservative prime minister and a Conservative chancellor," he replies.

David Cameron - back on stage in Bristol - is asked by a reporter to describe Nick Clegg in three words. The PM declines the invitation, instead replying: "You will find the minor parties saying increasingly desperate things." Ouch.
