The vast majority of Conservative MPs are continuing to back the PM, with parliamentarians on the opposing benches using the findings of the report to call for his head.
Mr Johnson said he takes "ultimate responsibility" for No 10's failings during the scandal, which spanned 20 months.
Sir Keir Starmer used the report to deflect from an investigation into his own potential lockdown rule-breaking.

Despite most Tories standing by their man, Bournemouth MP and former minister Tobias Ellwood, took aim at Mr Johnson saying: "This is a damning report about the absence of leadership, focus and discipline in No 10 – the one place where you expect to find those attributes in abundance.

Ms Gray's conclusion noted that many across the country "will be dismayed" at the behaviour of many No10 staff.
She also said: "Whatever the initial intent, what took place at many of these gatherings and the way in which they developed was not in line with Covid guidance at the time.
"Even allowing for the extraordinary pressures officials and advisers were under, the factual findings of this report illustrate some attitudes and behaviours inconsistent with that guidance."
