Line of Duty creator Jed Mercurio has taken a swipe at Boris Johnson after he appeared in police uniform during a raid in Liverpool.
Mr Johnson had been attending a raid linked to Operation Toxic involving officers from the British Transport Police and Merseyside Police in Liverpool on Monday.
The leading screenwriter also included a photo of Mr Johnson wearing a police hat and jacket.
Mr Johnson is under growing pressure to explain what happened in Downing Street last year when a Christmas party was said to have been held during coronavirus restrictions.
