On 25 June 1981 Defence Secretary John Nott announced that Chatham Dockyard would close within three years.

Unemployment in the area was already at more than 13% and the naval dockyard was the largest employer.

The BBC's Michael Buerk reported that the closure could push local unemployment to over 20%.
