Before we sign off, a quick look at the day's election news:

• The Labour leader, Ed Miliband said he was ready to lead the country as he unveiled Labour's general election manifesto . He said all policies were costed and would not require additional borrowing
• There were few policy surprises in the manifesto. Instead, the aim was to establish Labour's economic credentials and accuse the Conservatives of making unfunded pledges
• David Cameron dismissed the suggestion that Labour could deliver their promises without borrowing more - describing their pledge of fiscal responsibility as "not a conversion, but a con"
• Nick Clegg compared Labour's assertion that they have no plans for additional borrowing to "an alcoholic who consumes a bottle of vodka every day, saying they have no plans to drink more vodka"
• The Conservatives also got a bashing from Nick Clegg, who said he would refuse to go into coalition with the Tories if they insisted on £12bn in welfare cuts.
• The Greens unveiled their national campaign poster , saying the time for "half measures" was over
• The leader of UKIP has encouraged people to vote tactically in the election
• The Conservatives will say - at their manifesto launch on Tuesday- that they would extend the right-to-buy to housing association tenants in England

BBC political correspondent, Chris Mason, points out that Margaret Thatcher features on several of Tuesday's front pages.

He understands that David Cameron - at the launch of the Conservative manifesto on Tuesday - will flesh out proposals on the right to buy housing association properties…

He tells BBC's 5Live that Conservative activists regard the right-to-buy council houses as "hugely important" in the Thatcher years in wooing blue collar working-class voters.

Chris Mason says there's also talk of a Conservative announcement on the minimum wage.

"The Conservatives might try and outbid Labour on the subject of the minimum wage, which you wouldn't necessarily expect from a party that not all that long ago opposed the minimum wages' introduction. That's just the kind of politics I suspect that would put a smile on the face of the Chancellor George Osborne."

Labour's education spokesman Tristram Hunt gives his reaction on BBC Newsnight to Conservatives plans to give more people in housing association properties the right to buy their own homes.

He said: "We believe in people owning their own homes but unfortunately we have seen the lowest proportion of people buying their own homes [under the last government].

The Editor of BBC Political Research, David Cowling, writes:

TNS published a Scotland poll that gave the SNP 52%, which is the party’s highest rating since securing the same figure in the January 2015 MORI poll. Labour were left with 24% and the Lib Dems with 6%.

Elsewhere, ICM provided further excitement with a poll giving the Conservatives 39%, over Labour’s 33%. This is the highest Conservative rating since March 2012. However, in three other polls sampled over the same days as ICM, YouGov gave Labour a 3% lead and the two others, Ashcroft and Populus, had dead heats with Conservative and Labour both on 33%. Perhaps one clue to the difference was that ICM had UKIP on 7% - half the support registered for the party in the three other polls.

It will take some time before we can measure what impact, if any, this Week of Manifestos has on the polls. For the present logjam shows little sign of shifting..

Duncan Weldon, Newsnight's economics correspondent says there's a "big gap" between the Labour and Conservative plans. He says the Conservatives are aiming to bring the deficit down from £90bn this year to zero by 2020 while Labour plans to bring it down from £90bn to £30bn. He says: "That's a big difference. It's worth saying there are a lot of economists out there who think this is perfectly rational. Government borrowing costs are very low."
