East was appointed Chief Constable of South Wales Police in 1983. During the
UK miners' strike (1984–1985), East was Chief Constable of South Wales Police. Much as though the area was a key coal production area, East's careful policing meant that the area suffered few of the industrial relations problems associated with others areas of the British Isles. One of the key decisions East made was to address the problem of transporting coal from
Llanwern to
Port Talbot as a transport issue, running daily convoys of 140 trucks escorted by police cars and motorcycle outriders; none were stopped, and because East refused to use riot gear clothed police, none were attacked. East was also the Chief Constable in charge of investigation of the most serious incident during the Miners Strike. On 30 November 1984, a concrete block was dropped on the car of taxi driver and father of four
David Wilkie, killing him instantly. Political leaders united in condemning the killing: Labour's
Neil Kinnock called it an "atrocity" and Prime Minister
Margaret Thatcher said it was "an utterly despicable deed". A court in Cardiff convicted 21-year-old miners Dean Hancock and Russell Shanklin of Wilkie's murder, later reduced on appeal to
manslaughter. After a fierce campaign for their release led by the NUM's
Arthur Scargill and Labour MP
Tony Benn, the men were released on 30 November 1989, the fifth anniversary of David Wilkie's death. ==Welsh Rugby Union==
