A union official who resigned from his job at a giant oil refinery after a row over a Labour Party selection process has taken up a temporary post with Unite.

Stevie Deans left his job at the Grangemouth site in Scotland last year and decided not to seek re-election as chairman of Labour's constituency party in Falkirk.

Unite was accused of trying to sign up members to influence the selection of a Labour candidate in Falkirk, but always denied doing anything wrong.

Mr Deans was suspended by Grangemouth's owner, Ineos, over claims he used company time for political campaigning work, but his treatment prompted a vote for strike action, which led to a temporary shutdown of the plant.
