The Conservative party's manifesto threw out plans to place a cap on lifetime care costs, but in what has been described as a desperate attempt to get her election campaign back on track, the Prime Minister has pledged to introduce a cap on lifetime care costs.
Labour said many were referring to it as a "dementia tax" and that it would mean "more people having to pay for care in their own homes".
In her first major TV interview of the election, hours after the policy change, May looked uneasy as she insisted the choice for British voters on June 8 was between her "strong and stable" leadership - the campaign slogan she has repeated since campaigning began - and the "coalition of chaos" under Labour leader Jeremy Corbyn.
Appearing visibly angry, she accused Mr Corbyn of resorting to "fake claims, fear and scaremongering" over the impact of her plans and chided reporters who asked about a dementia tax for "using terms that have been used by the Labour Party to try and scare people in this country". "We will make sure social care is properly funded", he said on Friday morning.
"And we must do everything we can to maintain peace in Northern Ireland and that's a commitment in this manifesto and it's one that wouldn't have happened if we hadn't have a Labour government and it is exactly why we need a Labour government again".
Labour is now only nine points behind Prime Minister Theresa May's Conservative Party, which the poll put at 44 percent, only days after the main parties launched their manifestos.
The proposals, which would see elderly patients forced to pay for care in their own home if they have assets totaling £100,00 or more, have proven unpopular with Tory voters.
Coined the "dementia tax" by the Labour party but also adopted by right-wing media, highlights how someone suffering from Alzheimer's, which requires a heavy reliance on social care, would be less able to pass on their home to children than someone with an illness such as cancer, which is treated by the NHS. We were honest that we were going to have a green paper and would be consulting people on how the system operates.
A Survation poll published on Monday before her speech showed May's lead over Labour had halved to 9 percent, adding to a string of polls suggesting the gap was narrowing.
The opposition has focused on the Conservatives' social policies. She is unable to stick to her own manifesto for more than four days.
And she claimed that, despite her policy U-turn, she was best placed in a contest that would be about trust. "Families deserve to know exactly how much of their homes would be up for grabs now, not after the election".
The surprise announcement comes less than a week after Mrs May unveiled controversial plans for an overhaul of care funding, including reforms that would increase the number of pensioners paying for at-home service.
