Dominic Cummings is preparing to unleash a 'treasure trove' of secret information accusing Boris Johnson of personally being to blame for the UK's devastating coronavirus death toll.
The PM's ex-aide is said to have a store of damaging evidence from his time inside Downing Street that could spell disaster for his old boss.
It has emerged Mr Johnson allegedly told advisers he was ruling out any more "f***ing lockdowns" after the second bout of restrictions in November, vowing to avoid them regardless of the number of 'bodies'.
No 10 denies the claim. It comes amid a bitter spat between the PM and his former right-hand man, who had access to some of the most confidential information in government before he was booted out last year.
