Met chief says Zack Polanski undermined police with Golders Green post

Mark Rowley says Green leader's comments risk denting confidence of officers confronting dangerous' suspects

The Green party leader, Zack Polanski, thoughtlessly undermined the confidence of officers to deal with dangerous people by sharing a critical social media post after the Golders Green stabbings, according to the head of the Metropolitan police.

Officers were filmed detaining the suspect after two Jewish people were stabbed in the north-west London suburb on Wednesday.
