Parliamentary career
Mark Lazarowicz stood for the House of Commons, unsuccessfully, for Edinburgh Pentlands at the 1987 general election and again in 1992, but was defeated by Malcolm Rifkind on both occasions. He was elected as Member of Parliament for Edinburgh North and Leith in June 2001 and was re-elected in May 2005 and May 2010, for the now expanded Edinburgh North and Leith constituency. He was a member of the House of Commons Environmental Audit Committee. He previously served on the Environmental, Food and Rural Affairs Select Committee, the Scottish Affairs Committee and the Modernisation Committee. Between October 2010 and 2011 he was Labour's shadow Minister for International Development. Lazarowicz has succeeded in having two Private Member's Bills passed. In 2002 he piloted the Employee Share Schemes Bill through Parliament, and in 2006 the Climate Change and Sustainable Energy Bill,. He won the PRASEG Parliamentarian of the Year Award in 2006 for his work in promoting renewable energy. In 2008, he lodged a further Private Member's Bill to restrict ship-to-ship oil transfers, with the aim of preventing spillages in the Firth of Forth. In response, the government introduced regulations to restrict such transfers in April 2010 which were then delayed, but eventually were brought into force. In October 2008, Lazarowicz was made the Prime Minister's Special Representative on Global Carbon Markets and his report on the issue, Global Carbon Trading: a framework for reducing emissions was published in July 2009. He rebelled against the Labour government on the Iraq war vote in 2003, and on a number of other issues including the Digital Economy Bill and the Data Retention and Investigatory Powers Bill. He also opposed the Conservative government's Immigration Bill and retrospective legislation on workfare. Lazarowicz was defeated in the 2015 general election by the Scottish National Party's Deidre Brock. During the 2009 MP expenses scandal, Lazarowicz announced he would repay half of the more than £5000 expenses he had claimed for legal fees regarding the extension of the lease on his London flat,. Later he reversed his view, stating that his expenses were entirely within the existing parliamentary rules and that a lot of people and fellow MPs had questioned his decision to pay back the money.: "Why on earth am I bothering to pay back the money? That's actually the view which has come back from a large number of people I have been in contact with. Having said that I have said I will pay it back, so I'll pay it back, because I actually accept at the end of the day the fundamental principle that MPs shouldn't actually benefit from property they have acquired." In his audit of MPs' accommodation expenses claims, Sir Thomas Legg reported that Lazarowicz had no issues with his claims. He was therefore not required by Sir Thomas to make any repayments of his expenses.
