Discount grocer Aldi has mocked the outgoing-Prime Minister Liz Truss over her resignation.

The outgoing PM announced her resignation at No.10 earlier today, after 45 days in the position.

“I recognise, given the situation, I cannot deliver the mandate on which I was elected by the Conservative Party,” she said.

“I have therefore spoken to His Majesty the King to notify him that I am resigning as leader of the Conservative Party.”

This resignation five days after Truss sacked her chancellor, Kwasi Kwarteng, replacing him with Jeremy Hunt, the former foreign secretary and health secretary.

The news comes as Prime Minister Liz Truss has indicated that restrictions looking to ban multibuy promotions such as buy one get one free (BOGOF) deals on high in fat, salt or sugar products (HFSS) could be scrapped.

Set to come into play next October, the legislation – which looks to tackle obesity levels across the UK – will follow on from restrictions banning HFSS products from aisle ends, store entrances and checkout stations which rolled out across the retail sector last week.

The news comes as Iceland managing director Richard Walker has launched a bid to become an MP and has been named on the Conservatives list of approved parliamentary candidates.
