Jeremy Corbyn will warn that five more years of the Conservative Party in government would be ‘disastrous’ for Britain.
In a speech in London later on Wednesday, the Labour leader will go on the offensive and say that public services will be put at risk if Theresa May remains in Number 10 after the June 8 general election.
‘The futures of our NHS and schools are at stake in this election,’ Mr Corbyn will say.
‘Labour will invest in our people, schools and hospitals. We will cut class sizes, take a million people off the NHS waiting list and ensure people get the care they deserve.
‘By contrast, another five years of the Tories would be disastrous for our public services.’
Mr Corbyn will also seek to exploit the Conservative Party U-turn on capping social care following the ‘dementia tax’ row.
He will say 1.5 million older and vulnerable people will not have their care needs met under the Tory plans.
In addition, he will warn that 650,000 children will be ‘crammed’ into primary school classes larger than 30 pupils, and families will be nearly £450 worse off per child as a result of Conservative plans to scrap free school meals for 1.7 million children.
Mr Corbyn will highlight new analysis showing that under Tory plans, 5.5 million people will find themselves on NHS waiting lists in England by 2022.
But work and pensions secretary Damian Green accused the Labour leader of using ‘made-up numbers’.
He said: ‘Brexit negotiations start 11 days after people vote and are crucial to our economic security and the future of public services.
‘Made-up numbers from Corbyn cannot hide the fact he’s not up to the job of getting the deal we need.’
A television debate on BBC later will see representatives from seven parties facing each other.
Neither Mrs May nor Mr Corbyn is expected to take part, with the Tories represented by home secretary Amber Rudd instead.
Liberal Democrat leader Tim Farron, Ukip leader Paul Nuttall, SNP deputy leader Angus Robertson, Green Party co-leader Caroline Lucas and Plaid Cymru leader Leanne Wood will appear, along with a senior Labour politician.
