Mark Serwotka, head of the biggest civil service trade union and according to his critics, a member of the left-wing awkward squad. He's now on a collision course with the Government over plans to reduce public sector jobs. Morland Sanders profiles a union leader who so far this year, has fronted three national strikes.
He is perceived by some as an outdated trade union firebrand but he is committed to protecting the public sector from cuts to the kinds of job he did for nearly twenty years - a benefits officer in the south Wales valley of Aberdare.
