ON the day that Boris Johnson finally faced the music over revelations about a BYOB party on Downing Street, Prime Minister’s Questions was suitably rowdy.

The Tory leader was pummelled with demands to resign from opposition benches, while MPs on his own side had spent the morning publicly speculating about his job security.

Labour MP Toby Perkins rose to condemn the PM for “debasing” the office of Prime Minister.

Johnson did little to dampen the fury has he trotted out his now robotic response, urging MPs to wait for the conclusion of his own government’s inquiry into partygate.

It turns out the Tory MP thought this was the perfect opportunity to lobby for all new washing machines to be fitted with filters to catch plastic microfibres.

After the Speaker intervened and the hilarity subsided, the South Leicestershire MP condemned those who were “laughing at plastic pollution”.

Yet many suspected the Conservative of a desperate attempt to deflect attention from the Prime Minister.

SNP MP Carol Monaghan tweeted: “As Alberto Costa asks a question on washing machines, the chamber erupts. Inadvertent (and unintentionally funny) reference to dirty linen and public!”

It seems not everyone was buying Costa’s spin…
