Boris Johnson has made eleventh-hour representations to the privileges committee before it publishes a report which is expected to find that he deliberately misled parliament.
A spokesman for the inquiry said it was “dealing with” further submissions received from the former prime minister at 11.57pm on Monday.
It came as the panel of MPs examining claims that Mr Johnson lied to parliament over “partygate” met to conclude its inquiry.
Their findings were expected to be published this week after Mr Johnson quit as an MP over the investigation and claimed he was the victim of a “witch-hunt” in an explosive 1,000-word statement.
