A claim by a former PSNI chief constable that police suspected senior republicans had known about and “concurred” with a murder in 2015 “raises profound and troubling questions”, according to TUV leader Jim Allister.

Former IRA commander Gerard “Jock” Davison was shot dead in the Markets area of Belfast in May 2015.
