Shabana Mahmood has signalled she is considering a change to knife laws, following the murder of Henry Nowak.

The Home Secretary said she had not “taken any options off the table”, after Nowak’s father, Mark Nowak, called for a clearer definition in law of what a Sikh kirpan looks like.

Mark Nowak told ITV News: “I fully understand the need to carry a kirpan but surely that should be defined in law, in terms of size and type and whether it should be visible, and so on and so forth.

“And therefore, anything else should be made illegal.”
