Thomas James Greatrex[2] (born 30 September 1974) is a British Labour Co-op politician, who was the Member of Parliament (MP) for Rutherglen and Hamilton West between 2010[3] and 2015 and the Shadow Energy Minister from 2011 to 2015.

He moved to Scotland in 2004 to take on a role as a chief officer at East Dunbartonshire Council[4] then worked as Director of Corporate Affairs for NHS 24 between 2006 and 2007.

He latterly worked as a policy adviser for Scottish Secretaries Douglas Alexander, Des Browne and Jim Murphy.

As Shadow Energy Minister, Greatrex has criticised both sides of the debate over fracking, arguing that an "evidence-based" approach is needed and that whilst shale gas will not solve energy shortages in future, there might be some role for fracking under "strict regulation".

On 17 May 2013, he gave an interview to the BBC about allegations made by a doctor employed by Atos that the tests are unfair and 'skewed against the claimant'.
