He was elected general secretary of the RMT in 2002 following the death of former leader Jimmy Knapp.Image caption, A longstanding Millwall supporter, Mr Crow, seen here with his dog Castro, was not a member of any political party, and was often equally critical of Labour - especially New Labour - as he was of the Conservatives.Image caption, He was known for his hard-nosed tactics including strikes, most recently last month when parts of the London Underground network were shut down for 48 hours.Image caption, Mr Crow's class-based politics made him a regular cartoon villain for some newspapers. His salary package of about £145,000 was criticised, especially as he continued to live in a council house. He is seen here in his office.Image caption, Unison general secretary Dave Prentis said: "I am shocked and saddened to hear of the death of Bob Crow. Unison members will want to send their sympathy to his family and friends."Image caption, Manuel Cortes, leader of the TSSA rail union said: "Bob Crow was admired by his members and feared by employers, which is exactly how he liked it."
