Sir Stephen House to quit as Police Scotland chief constable

The Chief Constable of Police Scotland is to stand down from his post earlier than planned.

Sir Stephen House had come under pressure after the force failed to respond to reports of a car crash on the M9 motorway for three days.

He has also been criticised over armed officers being put on routine patrol and his force's policies on stopping and searching juveniles.
