Page "Scottish National Liberation Army" Paragraph 2

The previously most high profile act occurred in 1983 when letter bombs were sent to Lady Diana Spencer and to the Prime Minister, Margaret Thatcher.

The device sent to Thatcher was active and was opened by parliamentarian Robert Key: there was no explosion.

Busby fled to Dublin in 1983 after the letter-bombing campaign ; he was jailed in connection with that campaign in 1997.
