Ed Miliband has said his party would invest £2.5bn into the NHS within the first year of a Labour government.
"An investment not for an NHS that stands still but one that keeps up with the challenges of time", he said.
The Tory party has a heart former Prime Minister John Major has said.
Throwing his support behind David Cameron's campaign Sir John said: "I gave my lifetimes work to the Conservative party because I know them from the inside and they do care and they do help. They may not wear their heart on their sleeve, but it beats just as strongly to help people as the heart of any other political party in this country."
We will never all be born equal. Life isn’t like that. But it is the Conservative mission to make opportunities in life as equal as we can make them.
That is what first drew me to the Party nearly six decades ago. While Labour was, generously and big-heartedly, offering me a hand “out”, the Conservatives offered me a hand “up”.
Today there are many young people now who are people who are in just the sought of circumstances that I was then. They need a hand up as well.
Prime Minister David Cameron is "a mortal danger to the NHS", Labour leader Ed Miliband has said in Manchester.
Former prime Minister John Major said the Labour party have a history of ruining the economy.
Sir John, speaking in West Warwickshire said:
They blame the financial crash – but all one needs to do is pick up a history book. Every single Labour Government we have ever had – from Ramsay MacDonald to Gordon Brown – has ruined the economy. Every single time.
There’s a pattern. Labour wrecks the economy. The Tories repair it but become unpopular in doing so. Labour are re?elected and wreck it again. It’s time to break that pattern.
Ed Miliband accused David Cameron of "threatening the integrity of the United Kingdom" by talking up the prospects of Scottish nationalists in the General Election.
The Conservatives are stepping up their campaign on the dangers of nationalist influence by deploying former Prime Minister Sir John Major to deliver a stark warning that a minority Labour government propped up by SNP votes would be a "recipe for mayhem".
But Mr Miliband insisted there would be no coalition with the SNP and denied Nicola Sturgeon's party would hold the whip hand on policy, telling BBC1's Breakfast:
A Labour government led by me, what happens in that Labour government will be decided by me, not by the SNP.
I think David Cameron is playing fast and loose with the United Kingdom.
This is somebody who has given up hope of winning a majority. He is trying to boost the SNP. I think David Cameron is now threatening the integrity of the UK with the games he is playing. And I think Conservatives are now ashamed of what he is doing.
Former Liberal leader Lord Steel says Sir John Major does not understand Scotland.
He told the BBC Radio 4 Today programme:
The Tories are really doing the SNP a favour by bringing them to the centre stage of the campaign.
I think the consequence is we will end up with a minority government. Ed Miliband has made it clear he does not want any deal with the SNP.
With 16 days to polling on May 7, Sir John will say in a speech in the Midlands that a Labour-SNP administration would lead to "weak and unstable" government and wreck Britain's economic recovery.
Labour leader Ed Miliband has said a European Union plan to cut numbers of deaths of migrants crossing the Mediterranean does not go "nearly far enough" and warned it will be "a stain on the EU" if proper action is not taken.
Prime Minister David Cameron will join EU leader in Brussels on Thursday to discuss the 10-point plan, drawn up on Monday in response to the deaths of an estimated 900 people on a boat which capsized off the coast of Libya on Sunday.
The EU aims to strengthen its Triton patrolling service and seek a military mandate to seize and destroy people-smugglers' boats, backed by increased budgets for Frontex, which manages the borders of the 28-nation bloc.
But Labour leader Ed Miliband told BBC1's Breakfast the plan did not go far enough, asking: "We haven't really got to a situation, have we, where we just let people drown because saving them is somehow a price not worth paying? We cannot do that.
"Frankly, it is a stain on the EU if we don't take proper action."
