And so the last day before the last week of campaigning comes to an end and still the polls show no sign of either Labour or Conservatives pulling away. Tomorrow, the party leaders face another round of questioning on BBC TV. Today they were out and about campaigning hard:

• David Cameron promised to introduce a law guaranteeing no rise in income tax rates, VAT or national insurance if the Tories win the election
• Labour said it was a "last-minute" gimmick and suggested the Tories had a secret plan to cut tax credits
• The Liberal Democrats said voters would "simply not believe" the pledge unless the Tories spelled out where they would cut public spending
• Russell Brand released his interview with Ed Miliband . The Labour leader told the comedian he was wrong to say that voting was pointless
• UKIP leader Nigel Farage warned of an influx of Islamic extremists if Europe's doors were opened to large numbers of people fleeing conflict zones
• Nick Clegg laid down another condition for considering a coalition - he wants a £12,500 personal tax free allowance
• And the SNP could win all 59 Scottish constituencies, according to a new poll. Leader Nicola Sturgeon said she wanted Scotland's voice at Westminster to be "as loud and effective and as powerful as possible"

Responding to claims from the Treasury Minister Danny Alexander that the Conservatives came up with proposals to 'slash' child benefit and child tax credit, a Conservative spokesman told the BBC: "This is desperate stuff from Liberal Democrats who are now willing to say anything to try and get attention. We don’t recognise any of these proposals and to be absolutely clear, they are definitely not our policy.”

Labour's Andy Burnham says during the BBC's Newsnight debate that Labour would get money flowing into the NHS through the mansion tax and by cutting the bill for agency staff. He says: "We have to recruit more staff." Meanwhile the Liberal Democrat Norman Lamb repeats his suggestions for a non-partisan commission to come up with a "new settlement" for the NHS. Jeremy Hunt and Andy Burnham, more or less, agreed.

The Chief Secretary to the Treasury, the Liberal Democrat Danny Alexander says he is lifting the lid on what he calls "secret Tory proposals" to limit child benefit and child tax credit to two children. Mr Alexander says the change would have meant a cut of £3,500 in benefits for a family with three children. He says he blocked the plans and he lists the other policies he says the Conservatives were considering.

• remove the higher rate child benefit from first child - an average cut of over £360 for every family with children
• means test child benefit - cutting £1,750 for a two-child middle income family
• remove Child Benefit from 16-19 year olds - a cut of over £1,000 for parents of a single child

Danny Alexander said:

It's the turn of BBC's Newsnight to debate the health service, with the help of a panel of health professionals. A former neurosurgeon Henry Marsh says he can't see how the NHS can make a further £22bn in efficiency savings. Answering the questions are Health Secretary Jeremy Hunt, Labour's Andy Burnham and the Liberal Democrat Norman Lamb. Mr Hunt says he agrees with Mr Hunt that the £22bn target will be "hard". One way to get costs down, he says, is to treat people earlier in the community

David Cowling, Editor BBC Political Research, says it's been a "quiet day" for GB-wide polls but not in Scotland where the pollsters are under pressure.

He says: "YouGov reported a one point Labour lead - 35% over 34% for the Conservatives with UKIP on 12%, the Lib Dems on 9% and the Greens 4%.

"MORI published a Scottish poll that created quite a stir - with the SNP on 54% and Labour 20%. The pressure on the pollsters in Scotland must be the greatest of all. The big SNP numbers they regularly generate could well reflect political reality but the potential for error is considerable.

"ComRes published their latest battleground polls for ITV, sampled in 50 Conservative marginals where Labour is second. Their poll suggested a 3.5% swing to Labour since 2010 and their gain of 40 of the 50 seats sampled.

"Lord Ashcroft also published three constituency polls: in Nick Clegg’s seat of Sheffield Hallam suggesting a one point Labour lead; Thanet South which indicated Nigel Farage two points behind the Conservatives; and Swindon South where Labour were one point behind the Conservative incumbent."

How to improve Britain's finances is the big issue of the election so how appropriate for a party leader to meet the Wallet Watcher group. Nick Clegg had a question and answer session with the group (which aims to educate young people about money) on a trip to Greater Manchester. Asked for his own money-saving tips, he suggested shopping around online and switching energy provider.

Ronnie O'Sullivan, much admired by snooker-loving Labour leader, Ed Miliband, has returned the favour. O'Sullivan, currently competing in the World Championships at the Crucible in Sheffield, has backed Labour's candidate in Sheffield Hallam. According to party website Labour List, external, O'Sullivan said of Labour candidate, Oliver Coppard:

The former Chancellor, Nigel Lawson, has told the Spectator magazine, external that it's been a mistake for the Tories to make a "flurry of promises". According to the Tory peer, they've detracted from a central message of economic recovery based on careful stewardship.

Lord Lawson does have kind words for his successor but five, George Osborne. He says Mr Osborne has done an "excellent job".
