What did Dominic Cummings say? As it happened - BBC News
Boris Johnson's former aide told MPs he tried to create a "structure" around the PM to stop "extremely bad decisions".
Science Committee Chair Greg Clark asks if the possibility of Covid variants were being discussed in September.

Cummings says he knew of variants in September, and if he knew about it then others would have too.

"I had specific warnings... from scientists who had been repeatedly proved right" on the possibility of Covid variants, he states.

"The government is still not acting properly, we still don't have a proper border policy," he warns.

Cummings says "as soon as you make the decision that you have to lock down" then the decision needs to be enacted "today".

He says this is what the data team was saying to the prime minister in September.

He says the PM was "enraged" when in September it looked like cases had risen again.

Cummings says he was of the view that "you need to whack [Covid] hard" immediately.
