Liam Dominic Byrne (born 2 October 1970) is a British Labour politician who has been the Member of Parliament for Birmingham Hodge Hill since 2004, and is currently the Chief Secretary to the Treasury.
Born in Warrington, Byrne was educated at Burnt Mill School in Harlow and the University of Manchester, where he obtained a First class honours in Politics and Modern History and became the Chief communications officer of the University of Manchester Students' Union. He also holds an MBA from the Harvard Business School where he was a Fulbright Scholar. He has acted as an advisor to Tony Blair. He is founder of the computer company e-Government Solutions Ltd, a provider of e-commerce solutions to government, and is an associate research fellow at the Social Market Foundation. Before working in Parliament, he worked for the multi-national consulting firm, Accenture and merchant bankers, N M Rothschild & Sons, before co-founding a venture backed technology company, eGS Group, in 2000. Between 1996 and 1997 he advised the Labour Party on the re-organisation of Millbank, and helped lead Labour's business campaign under the 'New Labour' scheme.
He was selected to contest the Birmingham Hodge Hill by-election following the resignation of the veteran Labour MP Terry Davis to become the Secretary General of the Council of Europe. After a very close contest, on 15 July 2004, the same day as Labour lost Leicester South in another by-election, Byrne held on with a majority of just 460. He made his maiden speech on 22 July 2004
