RMT union general secretary Bob Crow dies.

General secretary of the Rail Maritime and Transport union Bob Crow has died aged 52

In a statement on its website, the union said he died in the early hours of Tuesday morning.

London Mayor Boris Johnson, with whom he clashed over plans for the Tube, said: "I am shocked. Bob Crow was a fighter and a man of character."

Mr Crow was elected general secretary of the RMT in 2002 following the death of former leader Jimmy Knapp.

The BBC's political editor Nick Robinson said Mr Crow "was, some argue, the most successful union leader in terms of securing jobs and pay for his members".
