Amid a bitter election row over public spending, Sir Andrew Dilnot said he believed the two main parties were reluctant to discuss care reform for fear of being accused of plotting future tax hikes.

Sir Andrew - whose 2011 report laid out several key measures adopted by the government - described social care as the "biggest risk that isn't managed" that the country faces.

He said: "Four out of five people are going to need social care before they die, we should grow up and face it."

"I think politicians are reluctant to talk about it firstly because they're worried about anything that means an increase in public spending and therefore possible taxation," he added.

The implementation of a cap on care costs, unveiled by Boris Johnson, was delayed in 2022 until October next year.

The policy promised to limit the amount anyone in England will spend on personal care over their life to £86,000.

Speaking to Sky News on the campaign trail, Rishi Sunak said those charging reforms were still "on track".

Labour has not explicitly committed to the cap in its manifesto, but a party source confirmed that it would also bring in the reforms as planned.

While the Liberal Democrats have made social care a key part of its policy offering, the sector has barely featured in the campaigns of the main two parties.

The idea of a cap was first suggested by the Dilnot Commission and put into legislation in 2014.

However its planned implementation in 2016 was delayed by the David Cameron government on cost grounds.

An attempt to reform the sector during the 2017 election was widely seen as the reason for Theresa May losing her Commons majority.

In his first speech as prime minister in 2019, Boris Johnson said he had a "clear plan" to "fix the crisis in social care once and for all".

Reforms were announced in 2021 alongside an increase in National Insurance to fund the wider sector.

However this tax rise was reversed under Liz Truss before the broader changes were delayed under Rishi Sunak.

It means that many people requiring care are still potentially liable for costs that can stretch to thousands of pounds per month.

Sir Andrew said the lack of suitable social care was also having a "knock on effect" on the NHS as older people ended up stuck in hospitals.

"Lots of elective procedures rely on being able to have a bed and if you've got one older person… in hospital for twenty days more than is needed, that could easily mean ten hip replacements not being able to happen because there isn't the bed space," he said.

Care bosses have also highlighted staffing shortages caused by low pay as another key problem in the sector while councils have called for more funding from the government.

Speaking to Sky News, Rishi Sunak said £8.5bn was put into the NHS and social care shortly after he became prime minister and that his government had focused on "improving the link between social care and hospitals… but also investing in the workforce".

A Labour source said "the social care chapter in our manifesto includes a commitment over the next decade to build a national care service, and first steps of a fair pay agreement for care workers".

Shadow health secretary Wes Streeting also admitted that he wanted a "more ambitious" social policy but that it had to be "affordable" to be included in the manifesto.
