'This is a truly extreme proposal,' the Reform Treasury spokesman warned

Reform's Treasury spokesman Robert Jenrick has branded Andy Burnham's social care plans as “fantasy” as he warned hard-working Britons are set to be hit by more taxes.

It has been speculated that Mr Burnham will introduce a death tax to fund social care reform, which Mr Jenrick described as a “cruel and punitive” levy.

He began: “Andy Burnham's levy is different. It has no threshold, no allowance, no minimum, no limit whatsoever.

“Everything goes in, the family heirlooms, your mother's wedding ring.”

The MP for Newark also said Britons are amongst the most heavily taxed people when they die.

“Of the 38 OECD nations, Britain already runs the fifth harshest death tax regime."

Mr Burnham's death tax and our existing inheritance tax would cost families almost £30billion a year.

"Britain would become the single worst place to give money to your kids in the Western world.

“It would be worse than that because it would also make the UK the only country in the whole of the West to tax all savings with no allowance whatsoever.

Mr Burnham suggested a three-point plan to reform social care in the UK yesterday, announcing there will be fairer pay for carers, cross-party collaboration on the issue and moving the Baroness Casey report forward to publication in 2027.

A death tax has been floated as an option to fund social reform, which is estimated to cost £18billion.

The Prime Minister recently admitted that “difficult decisions” would have to be made on taxation to help fund social care.

The former Greater Manchester Mayor has vowed he will “stick to the manifesto” Labour put forward on levies, sticking to his predecessor Keir Starmer's fiscal rules.

It comes as research commissioned by Reform UK found that a possible death tax raid would cost voters in Makerfield £50,669.

The Greater Manchester seat is Mr Burnham’s constituency, where he stormed to victory and returned to Westminster to succeed Sir Keir.

Reform UK's research found the cost for the average mortgage-free homeowner in England and Wales could be £74,737.

Makerfield's £50,000 figure is based on data compiled by the Office for National Statistics showing the median price of a home in Makerfield was just under £200,000.

The median price rises to around £295,000 across England and Wales, with the South East of England and London likely to be the hardest hit.
