Cabinet Office Minister Michael Ellis took the question, and has told MPs that Prime Minister Boris Johnson was made aware of a formal complaint against Pincher in late 2019 - but he "did not immediately recall this conversation... about the minister" when he was asked about it last week.
"As soon as he was reminded, the No 10 press office corrected their public lines," Ellis said.
Boris Johnson acted with probity at all times, he added.
