Scotland's main political parties are looking to build on last night's ITV debate.
The seven-way programme was the only one to feature both Ed Miliband and David Cameron, with two more planned before the vote.
Alex Salmond will be in North East Fife, campaigning in St Andrews where studied before travelling to Cupar.
Jim Murphy and Glasgow Central Labour candidate Anas Sarwar will be in Glasgow city centre to highlight an increase of 14,000 Scots on zero hours contracts in Scotland in the last year.
He'll say: "The experts at the Office of National Statistics have reported that the number of people on zero hours contracts in Scotland has exploded by over 30%, the second highest rise in the UK, and it is simply wrong.
“Scotland succeeds when working people succeed, that’s why Labour will call time on exploitative zero hours contracts. We’ll give hard working Scots a legal right to a regular contract.
“The SNP had a chance to support Labour on this, and they bottled it.
“Scottish Labour tried to ban exploitative zero hours contracts from public contracts last year, but our plans were blocked by the SNP joining forces with the Tories in the Scottish Parliament.
“Only a Labour Government will ban exploitative zero hours contracts.
The Scottish Conservatives will reveal why the General Election can only be a two horse race.
At the Good Friday race meeting in Musselburgh, punters will see how much other political party leaders are lagging behind in the race to Number Ten.
Party leader Ruth Davidson will be showing a mock up betting board revealing the odds.
Alistair Carmichael will launch a nationwide weekend of campaigning for the Liberal Democrats in support of the £825 income tax cut that starts on Monday for working Scots.
Speaking on the campaign trail in the Borders with Berwickshire, Roxburgh and Selkirk, Mr Carmichael will set out the Liberal Democrats' record of action on income tax cuts and propose another £400 cut in the next parliament.
Mr Carmichael said these are the most important four days in the campaign so far.
"He said: Millions of people in Scotland will see the benefit of Liberal Democrats in government when their income tax goes down on Monday.
“In 2010, David Cameron said that we could not afford to cut tax for workers. Liberal Democrats in government proved him wrong. I am proud that we have helped deliver a £825 tax cut for more than 2.3 million working Scots.
“This is a tax cut for working people that the Conservatives said was not possible and Labour and the SNP did not want. It has been delivered by Liberal Democrats.
“As the campaign unfolds it is clear that with the Tories veering to the right on cuts and Labour and the SNP veering to the left with their borrowing plans, no other party will put taxes down for working people.
“We know that the Tories would never cut taxes for ordinary Scots on their own. Labour and SNP borrowing plans mean we would have to spend more money paying off debt rather than ensuring workers can keep more of the money they earn.”
Patrick Harvie, Co-convener of the Scottish Greens, will join some of the party's Glasgow MP candidates as they also campaign in the city centre.
Candidates and campaigners will highlight the Scottish Greens' manifesto pledge of bringing the railways back into public ownership.
Scottish Green Party membership has surged to over 8,600 and, for the first time, candidates will stand in the majority of Scotland's 59 seats - including all seven seats in Glasgow.
In the recent Ashcroft poll Greens were on 10% in Glasgow North - one of the party's target seats along with Edinburgh East.
