Jeremy Corbyn has accused Boris Johnson of playing roulette with family finances by risking a huge hike in food prices with a no-deal Brexit .

Analysis shows crashing out of the EU will add £220 to shopping bills next year – almost enough to feed the average family for a month.

Experts at the University of Sussex estimate prices will rise by around 7%, due to tariffs and supply chain issues.

Dairy could leap by 9.8%, meat 2.9% and oils and fats by as much as 13.2%. It comes as the Bank of England warned no-deal would further hammer the pound.

Mr Corbyn told the Mirror: “In threatening the country with a totally avoidable no-deal Brexit, the Prime Minister is gambling with people’s lives.

“The impact on food prices, jobs and our manufacturing industry will be disastrous.

“After nine years of austerity holding down people’s pay, with foodbank use at an all-time high and with millions of people living in poverty in one of the richest countries in the world, a hike in food prices will be unaffordable for many families.”

Mr Corbyn urged the Prime Minister to rule out no deal and concentrate on “improving the lives of people struggling to get by.”

As the Labour leader urged the PM to rule out a “disastrous” no-deal, Mr Johnson showed no sign of backing down.

He took delivery of a £500 “Brexit countdown” clock at No10, a day after party chairman James Cleverly unveiled one at Tory HQ.

Sainsbury's, the Co-Op, Lidl and Asda have warned that a No Deal outcome could lead to empty shelves and rising prices.

And Sainsbury's warned last month that a No Deal exit in October would be particularly difficult to respond to because of strained warehouse capacity ahead of Black Friday and the Christmas holidays.

Oils and fats are likely see the biggest increase, rising by 13.2% according to figures provided to the House of Lords EU Energy and Environment Subcommittee by the University of Sussex’s Trade Policy Observatory.

They said dairy products were likely to rise by 9.8% and meat by 2.9%.

Labour's analysis of the figures found a 7% average rise would mean household spending on food would increase by £220 a year.

This is equivalent to 3.64 times the average weekly shop - almost enough to feed the average family for a month.

Number 10 insiders increasingly believe no deal is the most likely outcome on October 31, despite the Prime Minister’s assurances it was a “million to one” chance.

The Treasury unveiled plans to blow another £2.1 billion preparing for no deal on Wednesday, as the Halloween deadline loomed closer.

Meanwhile, a new poll suggests that almost three-quarters of Britons do not expect Boris Johnson to be able to agree a deal with the EU before October 31.

Some 74% of Britons do not think the UK and the EU will be able to agree a deal before the deadline, according to pollsters Ipsos MORI.

In the event of a no-deal Brexit, 40% of the public think that they understand what will happen "very well" or "fairly well" compared to 54% that say "not well" or "not well at all".
