The Daily Politics

Theresa May has arrived for the Conservative manifesto launch in Halifax, west Yorkshire. So we should be getting under way soon.

The Daily Mail's Quentin Letts is at the launch and talking about the atmosphere.

"It's very old-fashioned," he says, "there's intense worry about whether everything is perfect".

"We haven't had this in the other manifesto launches. This is going to be a much more methodical event, I suspect." he says.

The BBC's assistant political editor Norman Smith says Mrs May's manifesto shows a break with the Cameron years, with many flagship policies of the previous government being "junked".

"Out" are the tax lock, the pension pledge, the end of free school meals - and "forget" the idea of a cap on social care, he says, pointing out that areas of society protected from the "blast of austerity" - such as pensioners - are now in her sights.

Theresa May is saying this is not just a Brexit show, it's a "statement of intent and a very ambitious agenda".

• £2bn a year extra ring-fenced for social care
• Finish the job of implementing a cap on the cost of social care already legislated for.
• Introduce a statutory independent budget monitoring agency for health and care, similar to the Office for Budget Responsibility. This would report every three years on how much money the system needs to deliver safe and sustainable treatment and care.
• Raise the amount people can earn before losing Carer’s Allowance from £110 to £150 a week, and reduce the number of hours’ care per week required to qualify.

Here's what Labour has pledged on social care:

• £8bn extra for social care over the lifetime of the next Parliament, including an additional £1 billion for the first year
• A maximum limit on lifetime personal contributions to care costs, raising the asset threshold below which people are entitled to state support, and providing free end of life care.
• £3bn a year, funding route to be consulted on but options include wealth taxes, an employer care contribution or a new social care levy.
• An increase in the Carer’s Allowance for unpaid full-time carers to align the benefit with rates of the Jobseeker’s Allowance.
• Create a National Care Service for England.

It looks like the Prime Minister has arrived in her bus.

Looks like it was less glamorous for the media.

Willie Rennie explains why he supports a second Brexit vote but not one on Scottish independence.

We'll be looking for a little more detail in the soon-to-be published Conservative manifesto.

So far we know winter fuel payments for pensioners will be means-tested. Means-testing for social care would also take in the value of a person's home, while £100,000 of it would be ringfenced.

However, until we get the costings, it is not clear whether any extra money is being put in the system or just a redistribution.

We don’t currently know whether there will be a net gain or loss for the population in terms of how much they have to pay for care - the amount of assets you can keep is more generous but at the moment the cost of your house is not included in the means test for home care (it is for residential care) so this will bring more people into paying for their own care.

We don’t know either how many of the roughly 750,000 people who receive council-paid home care own their own homes.

Victoria Derbyshire

Minutes to go before the Conservative manifesto is unveiled and ex-work and pensions secretary Iain Duncan Smith's been speaking to the Victoria Derbyshire programme.

He says the Conservatives are trying to grapple with the cost of social care.

Speaking about the decision to means test the winter fuel allowance he says it's the right time to have it linked to earnings or to inflation, which "will allow the government the flexibility to target social care".

"That's the big challenge that face all of us at the moment," he said.

When he was running the Department for Work and Pensions he said it was "a constant area of frustration that we shoveled a huge amount of money out of the door" by way of winter fuel allowance to those who didn't need it.

"People used to spend it on many things and many wanted to hand it back, but there was no mechanism to do it," he said.
