In an undercover BBC Panorama report last week, police shared racist views about Muslims and made sexual quips about women being detained.

Neville Lawrence, whose son Stephen was murdered by racist thugs in 1993, speaks on the issue of institutionalised racism, misogyny, and corruption among Met Police.

“For many people, including myself, the latest reporting on racism, corruption and misogyny in the Met Police comes as no surprise.

“The only way to fix the Met Police is for the leadership to accept its diagnoses and take the medicine. But Mr Rowley will not do that. Even now he is refusing to accept that the Met is institutionally racist. It’s causing resentment in the black community and the community knows that if anything is wrong, or there is a situation involving the police, they can’t call the Met because they’re not going to do anything. This film shows why.

“They’re not doing their jobs. They’re supposed to be looking after the interests of everybody, no matter what you look like. This is not just about getting rid of officers, it’s about building a Met that reflects London. But if you don’t take that medicine then you’re going to die. Simple as that.”

Undercover reporter Rory Bibb spent seven months as a detention officer in the custody suite of Charing Cross police station in Central London. It was where officers had previously joked about raping women, domestic violence and racism. That led to commissioner Dame Cressida Dick stepping down.

The new allegations come on the third anniversary of Sir Mark replacing Dame Cressida Dick with a mandate to address deep concerns over the Met’s culture.

Among officers in the film are Sgt Joe McIlvenny, who allegedly described sexual adventures to colleagues, PC Phil Neilson who spoke out against foreigners and PC Martin Borg who said Muslims were a big problem. One off-duty officer says about immigrants: “Either put a bullet through his head or deport him.”

The officer then said he’d use a weapon on some “and let them bleed out”.Another, overseeing a woman being detained wearing police fancy dress, said: “I’ve paid to see women dressed like this.” One PC, bragging about a colleague stamping on a detainee’s leg, appears to say he offered a false statement.

Another said if suspects refuse fingerprints, he could snap their tendons.
