The Commons standards watchdog should hold Nigel Farage to account over his “dangerous comments” following the week’s violent disorder in the wake of the Southport murders, a Liverpool MP has said.

Kim Johnson, Labour MP for Liverpool Riverside, said Farage’s comments “cannot be left to fester” and should be examined by the parliamentary standards commissioner.

Farage has released two videos since three children were murdered in Southport last week. In the first, he questioned whether police were withholding information about who was responsible for the murders.

It came at a time when false information was circulating on social media that a Muslim asylum seeker was responsible, which fuelled disorder at a mosque in Southport.

In a second video, Farage challenged Keir Starmer’s argument that the violent protests were the fault of the far right, saying it was “a reaction to fear, to discomfort, to unease that is out there shared by tens of millions of people”.

However, several members of the public claim on social media to have submitted complaints about the Reform leader to the parliamentary standards commissioner, who can investigate any behaviour that brings parliament into disrepute.

Johnson said: “Nigel Farage’s dangerous comments cannot be left to fester. He is the voice of the EDL [English Defence League] in parliament, using his platform to spread fear and misinformation. Tensions are high and our politicians should be doing everything in our power to advocate for peace and unity, and support our communities standing resolutely against the racism and hatred displayed over the last few days. With so much at stake, we need urgent action from the Commons standards committee and the police to hold him to account.”
