Under-fire Prime Minister Boris Johnso n faced a damning speech from Keir Starmer in the House of Commons on Monday.
The leader of the Labour Party said that the "desperate" Prime Minster "gleefully treats what should be a mark of shame as a welcome shield".
Johnson has faced repeated calls to resign from both opposition and his own benches in Parliament, amid fury at the Partygate scandals at Number 10. He even faced a withering question from former PM Theresa May.
The alleged parties, some of which are also under investigation by the Metropolitan Police, were subjected to a report by civil servant Sue Gray.
Gray has been tasked with pulling together testimony and evidence about parties at Downing Street during lockdown.
The full report with details has not been released. Gray was forced to publish the first part without any inclusion of evidence as the police probe is still ongoing.
The publication of the update led to Johnson addressing the findings with an apology, but he also resorted to accusations against the opposition leader.

What did Keir Starmer say to Boris Johnson?
The PM apologised for the findings of the report, telling the House: "I get it and I will fix it."
"It's no use saying this or that was within the rules and it's no use saying people were working hard. This pandemic was hard for everyone," he added.
In response, Starmer said: "Funerals have been missed, dying relatives have been unvisited. Every family has been marred by what we have been through. And revelations about the Prime Minister’s behaviour have forced us all to rethink and relive those darkest moments. Many have been overcome by rage, by grief and even by guilt.
"Whatever people’s politics, whatever party they vote for, honesty and decency matter. Our great democracy depends on them. Cherishing and nurturing British democracy is what it means to be patriotic. There are Conservative members who know that, and they know that the Prime Minister is incapable of it. "
SNP Westminster leader Ian Blackford was kicked out of the chamber as he refused to withdraw his claim that Johnson had knowingly lied to the house.
What did Sue Gray's report say?
The full report has not yet been published, but the update criticised "failures of leadership and judgement" in 10 Downing Street.
Gray revealed that police are looking into 12 gatherings.
Police have since said they have received "well over 500 pieces of paper, about a ream and a half, and over 300 photographs".
