SIR KEIR STARMER sparked fears that he is putting Britain “up for sale” by vowing today to “rip up” bureaucracy in a bid to attract global investment.

The Prime Minister said it was “time to upgrade the regulatory regime” as he rolled out the red carpet for chief executives at a summit in the City of London.

Deals worth tens of billions of pounds were expected to be confirmed at the Guildhall, with guests also invited to an exclusive reception at St Paul’s Cathedral, attended by the King and featuring a performance by Sir Elton John.
