The Foreign Secretary appeared to say “b*******” while dismissing the veteran left-winger’s attack on the Brexit speech.
Mr Corbyn suggested Mr Johnson had briefed that the Working Time Directive – an EU regulation which limits an employee’s working week to 48 hours – would be scrapped after Brexit, sparking a rather unparliamentary response from the Foreign Secretary.
Addressing MPs from the Dispatch Box, Mr Corbyn said: “In December, the Foreign Secretary and the Environment Secretary gave a briefing that the Working Time Directive would be scrapped.”
At this point, cameras in the House of Commons panned across the chamber to Mr Johnson, who appeared to suggest Mr Corbyn was speaking “b*******”.
Mr Corbyn continued: “The CBI and the unions are very clear that they are not looking for a bonfire of regulations, quite the opposite.
“The only party that wants to scrap workers’ regulations and protections are the party opposite.”
The feisty PMQs session was filled with jabs from either side of the chamber, with Prime Minister Theresa May launching her own attacks at Mr Corbyn.
However, the Prime Minister also delivered a message that will likely please Brexiteers, declaring Britain’s will have a choice about where their new blue passports are made.
The Prime Minister was asked to “commit to doing all she can to support our manufacturers, our innovators and making our new blue passports truly British” by Chris Green, MP for Bolton West.
Mrs May said: “I think it is absolutely right that after we leave the European Union we return to deciding the colour of passports that we want, not what the European Union wants.”
She, however, said the bidding process would be open and fair with two French firms bidding for the contract.
