Reform UK and Restore Britain are politicising pain and using the Sikh community as a “scapegoat” following Mr Nowak, a Labour MP said.
Tanmanjeet Singh Dhesi, the Labour MP for Slough, earlier accused them of trying to “politicise people’s pain”, insisting the kirpan was not used in the attack.
Addressing the Commons on Tuesday, Mr Dhesi said he was “deeply saddened by the murder of Henry Nowak”.
He continued: “What’s very galling is that the likes of Reform, Restore, and the far-right decided to politicise people’s pain, attacking the Sikh community for wearing the kirpan and wanting it banned, even though the kirpan was not used in this violent attack.
“And they’ve decided to scapegoat and throw under the bus an entire community based on the actions of one violent murderer.”
