Tory MPs have been criticised for jeering Jeremy Corbyn over his green tie, which he wore as a sign of respect to those who died in the Grenfell Tower fire.
The Labour leader wore the accessory for a debate after report into the disaster that killed 72 people was published.
As relatives of those killed looked on from the public gallery, members from the Conservative benches mocked him for the bright tie.
Theresa May, who was prime minister when the blaze took hold of the west London building in June 2017, could be seen admonishing them by stressing the tie was to mark the tragedy.
Corbyn’s spokesman said: “I think that’s fairly contemptible. He was wearing a green tie as a mark of respect for the victims of the Grenfell disaster.
“I think those Tory MPs mocking his tie would be better supporting justice for the families and the victims of the Grenfell Tower fire and those who died in similar conflagrations and to deliver safety and protection for people living in tower blocks all over the country.”
Shadow education secretary Angela Rayner was also critical, accusing some Tory backbenchers of a “shocking lack of awareness”.
Corbyn was paying tribute to the outgoing Commons Speaker John Bercow ahead of the Grenfell debate when the mocking came.
He thanked the MP for having “reduced some of the strange customs and garments that people wear in this building”, in a reference to the sometimes archaic dress code.
Some Tories interrupted by loudly heckling Corbyn.
“I know you’re all jealous of my tie but it’s OK,” he shot back.
Tory backbencher Huw Merriman later remarked on the garment after complimenting Bercow on his Arsenal tie.
“I have worn mine as well but I am sorry the leader of the Opposition has not worn his,” Merriman added.
