Theresa May has no mandate for the kind of Brexit she is pursuing, Green party co-leader Caroline Lucas insists.

"Yes there was a vote to leave, but it's not clear what that leave looks like in practice, which is why we say it's right for the British public to have a final say on the deal and not just MPs.

"If they like it then fine but if they don't we should have that right to remain inside the EU."

EU nationals in the UK should have "their future guaranteed now", and not be used as "bargaining chips", Ms Lucas adds.

The Greens would protect the body of EU law that specifically protects the environment, adding that the legal architecture needs to be there to enforce that law.

"This election is about what kind of future we want for our children - it's about protecting our values of openness, of compassion of cooperation," she says.

Conservative plans to change social care funding in England have been derided by UKIP as "stupid" and the "worst public policy proposal of recent years and the nastiest too".

Speaking at press conference earlier, spokesman Patrick O'Flynn said the "death tax" could not be allowed to be implemented in its current form.

Mr O'Flynn said it was a "Russian roulette" approach to funding social care and older voters would not be "brainwashed" into voting against their financial interests on such a huge scale.

Green co-leader Caroline Lucas, the party's only MP, takes up the microphone to stress that the "Green guarantee is about hope".

"I can't remember a time in my own life time where the future has felt more uncertain - with Brexit, with accelerating climate change, with the NHS in crisis," she says, adding there are also threats to the UK's economic future, security and the planet.

Greens will continue to set the agenda with "bold policies to transform people's lives", including a pilot for a basic income scheme and a shorter working week, she says.

Ms Lucas stresses that her party will protect the NHS and take the private sector out of it with an NHS Reinstatement Act.

Launching the Green party election manifesto, co-leader Jonathan Bartley says the programme contains "big, bold ideas" which "with the right political will, are possible".

He says the policies are "caring" because they are striving to end inequality and are committed to redistributing wealth and power.

"We've the fifth largest economy in the world," he says. "In such a country, no renter should have to live in damp, cold, neglected accommodation."

No-one should have to wait 10 hours on an emergency ward before getting the care and attention they need, he says.

"We can have a different future - one where we all have the security and choices we deserve, and for a basic income that allows us to fulfil our potential and yes, our dreams."

Conservative plans for social care funding are "a callous blow" which will affect nine out of 10 English homes, Lib Dem leader Tim Farron claims.

After speaking to carers in Manchester, he said:

Using the example of a young person with a family who has multiple sclerosis and needs care, he says: "You will find if you have to move into care, your home will be up for grabs - that's the clear understanding behind this scheme."

For an elderly couple, where one partner has to go into a home and one stays in the family residence "that family home is now up for grabs", he says.

Back on the cost of social care, Labour front bencher Catherine West asks if it is in the government's gift to decide "what children should inherit or not", adding: "That doesn't seem to me a very Tory idea."

Ms West claims "part of the problem" was when Lib Dem former health minister Norman Lamb was in government "they cut out £4bn" from the social care budget.

"And that's why we have this sense of crisis now," she says.

Mr Lamb retorts that in 2010 the coalition was faced with a £160bn a year deficit, so hard choices had to be made.

Former Lib Dem health minister Norman Lamb says it's "extraordinary" that the Tories are abandoning the commitment to a cap on care costs that was negotiated with Health Secretary Jeremy Hunt's involvement under the coalition.

"Everyone was protected against catastrophic loss" under that system, he says.

"The great unfairness is if you're a millionaire with cancer you'll get all your health costs paid for, but if you're someone with dementia, say in a small semi-detached house, you lose everything you've got."

Victoria Derbyshire challenges that, saying £100,000 of assets will be protected.

"But is it really protected?" Norman Lamb asks. "Protected against care costs, but what about other costs?" He cites "ongoing accommodation costs" as one example of that.

There used to be a broad political consensus behind the idea of a cap on how much people paid for social care, but now the "floor" introduced by Theresa May will mean most home owners who are not massively wealthy will end up paying for their care.

The price of the average house is £250,000. Under Mrs May's plans, you would have to spend £150,000 of that value until you are down to the £100,000 the Tories say they'll protect.

The feeling is the policy tends to penalise people suffering from one particular illness, predominantly dementia, over other conditions like cancer for which NHS treatment is paid.

With mental health issues, you're pretty much on your own, say critics.

UKIP's Patrick O'Flynn is holding a press conference now, specifically focusing on attacking Conservative policies on the elderly.

He says the Tories have made a play of ending "universalism" when it comes to benefits. But just a day after launching her manifesto scrapping the winter fuel allowance for some pensioners in England and Wales, Theresa May helped Scottish Tory leader Ruth Davidson launch her equivalent, promising to keep it for all pensioners north of the border.

"It's yet another example of the English and Welsh being treated as second class citizens within the UK," says Mr O'Flynn. He insists "there is no reasons why a millionaire pensioner in Edinburgh" should get the allowance but one in Essex shouldn't.

"It is the Barnett Formula that is behind this," he adds - that's the calculation used to work out how much money the devolved administrations get. And that's why UKIP wants to get rid of it.

The BBC is running an election panel, asking voters for their thoughts ahead of 8 June.

We asked:

Tax has become a big election issue. Who should be paying more and who less? What should our approach to taxation be and whose policies do you support if any?

Mandy, Worcester: "I believe that the highest earners should pay more tax stop taking money from people that are not well off."

Mark James, Stoke on Trent: "Companies should pay more tax and off-shore located people if they do business in the UK should pay no matter where their domicile is.

"The working people should pay less as they have always bore the brunt of taxation, more disposable income more money spent on ''luxuries''

Beatrice Benson, Shrewsbury: "I don't think it's fair for people who earn more to pay a larger percentage. The current tax policies still mean that more money is paid from wealthier individuals.

"Labour's policies would mean paying an extraordinary amount of tax, which the party don't seem to have specified, which is a coincidence."

The Conservative source also dismissed claims the winter fuel allowance could be restricted to only those elderly people receiving the pension credit.

This would mean 10 of the 12 million pensioners in England and Wales currently receiving the payment of between £100 and £300 a year would lose out.

No decision has yet been made about the level at which the means test would kick in, added the source.

Conservative sources have dismissed the prospect of any re-think over Theresa May's planned reforms to social care. This follows unease among Tory MPs and widespread criticism from charities and pensioner groups.

Foreign Secretary Boris Johnson also appeared to hint on Sunday at a possible review of the changes and said he understood "reservations" over the policy.

However, on Monday a Conservative source said: "We are not rowing back."

The source said a consultation had always been planned but this would only examine "the finer detail" of the policy.

The PM remains convinced the changes outlined in the manifesto are "the right policy", the source said, adding that Mr Johnson's comments were "innocuous" and did not signal a possible re-think.
