Campbell was first elected as an MP for Blyth Valley at the 1987 general election with a majority of 853 votes, and has often voted against the government on issues such as the Iraq War. He is an outspoken socialist. When the government nationalisedNorthern Rock in 2008, Campbell declared it "the People's Bank" and opened an account. In May 2009, during the high-profile MPs expenses scandal, Campbell agreed to return over £6,000 of the £87,729 he had claimed for furnishings in his London home. Campbell voted for Andy Burnham in the 2010 Labour Party leadership election after the resignation of Gordon Brown. He was critical of Ed Miliband's leadership of the Labour Party, referring to him as a "right winger". In 2013, he was one of 22 Labour MPs to vote against same-sex marriage, out of 255. Upon re-election in May 2015, Campbell announced that he would stand down at the next general election, although this did not materialise. Campbell was one of 36 Labour MPs to nominate Jeremy Corbyn as a candidate in the Labour leadership election of 2015 and one of a handful of Labour MPs to publicly support leaving the European Union. Campbell continued to support Brexit, and to vote against attempts to delay it, in subsequent parliamentary votes. He justified this by noting that "I am a leaver, and I always have been. MPs are elected, unlike the EU bureaucrats, and if people don't like how MPs vote then they can get rid of us and that's how it should work." Campbell was one of 13 MPs to vote against triggering the 2017 general election. Having previously said he would stand down at the next election, he changed his mind, stating: "It was my intention to stand down at the next general election, however due to circumstances following the announcement of the snap election I have decided to stand again for Blyth Valley." In June 2019, Campbell confirmed that he would stand down as an MP in the following election, which was later confirmed for December 2019. He subsequently said he would back the Conservative government's deal to leave the European Union.
Personal life
Campbell married Deirdre McHale in 1967, who serves on Northumberland County Council. They have five sons, including a set of twins, and one daughter. While he served as an MP, Campbell had a reunion with a half-brother whom he had not known due to the latter's adoption. In September 2016, Campbell underwent chemotherapy after being diagnosed with stomach cancer. He returned to Parliament on 30 November 2016 and was welcomed back during Prime Minister's Questions. His interests include horse racing.
