Covid: No 10 Christmas party claims unsubstantiated says Raab
Dominic Raab has said reports of a Christmas party taking place in Downing Street last year were unsubstantiated and based on anonymous claims.
London was under Tier 3 Covid restrictions at the time.
Speaking to the BBC's Andrew Marr, the deputy prime minister said the guidance at the time had many caveats the public were trying to balance.
