Martyn David Jones (born 1 March 1947) is a former British Labour Party politician who was the Member of Parliament (MP) for Clwyd South from 1987 until his retirement at the 2010 general election.

Early life

Born in Wrexham, he attended Grove Park Grammar School (now Rhosnesni High School) on Penymaes Avenue in Wrexham. He went to Liverpool College of Commerce, then completed a BSc in Microbiology at Liverpool Polytechnic, then an MSc at Trent Polytechnic.

He is a microbiologist, and worked at the Wrexham Lager Beer Company from 1969 until June 1987 before his election to the House of Commons.

Jones was an opposition whip from 1988 to 1992, and under John Smith's leadership of the Labour Party, he was an opposition spokesperson for Food, Agricultural and Rural Affairs from 1994 to 1995.

In 2006 The Mail on Sunday newspaper reported that Jones had repeatedly swore at a House of Commons Security Officer. Jones denied the Mails allegations. He took the paper to the High Court to sue them for inaccuracies in the story. He called the article a "grotesque distortion" and was eventually awarded £5,000 in compensation. The paper also had to pay £300,000 in legal costs.

Jones has been a vocal campaigner on the issue of dormant bank accounts in the UK. The MP has campaigned since 2001 for the issue to be brought to the forefront of British political life. His work on the subject was praised by senior ministers, such as the Labour Chancellor of the Exchequer Alistair Darling.

On 7 May 2009, Jones announced that he would retire at the next general election.
