Newly released cabinet papers have revealed Margaret Thatcher's government considered sending in army troops at the height of the miners' strike in 1984.

They also show mineworkers' union leader Arthur Scargill may have been right to claim there was a "secret hit-list" of more than 70 pits marked for closure.

Other papers from 1984 reveal warnings of violence outside the Libyan embassy, in which WPC Yvonne Fletcher was killed.
