He was selected to contest Stockton North at the 1983 general election, securing the nomination following the defection of the sitting Labour MP Bill Rodgers who was one of the original gang of four who set up the Social Democratic Party in 1981. Cook won the seat with a majority of 1,870 with Rodgers finishing in third place behind the Conservative candidate. He served as Opposition whip under Neil Kinnock from 1987 to 1992. He was a member of the Speaker's Panel of Chairmen in the 2005–10 parliament. He was a leading opponent of gun control following the Dunblane massacre in 1996, and it was reported that he once asked the Tory MP Andrew Mackay to "step outside for a fight". In the 2005 political year, the Public Whip found Cook to be the 38th most rebellious MP and he had recently become known for his dissent concerning the controversial ID Cards and Racial and Religious Hatred Bill. He had the large former ICI site at Billingham in his constituency and was a supporter of Hartlepool FC.
In January 2008, Cook was de-selected by his local constituency Labour Party when choosing its candidate for the next general election in favour of Alex Cunningham. In April 2010 he announced that he would stand as an independent in the general election. In the 2010 general election, he stood as an independent, coming in fifth behind Cunningham, Ian Galletley, Philip Latham , and James MacPherson. Cook received 1,577 votes, 4.0%, and lost his deposit.
£5 expense claim
In May 2009, The Daily Telegraph revealed he had tried to reclaim, as an expense, the £5 that an assistant had donated during a service at Stockton Parish Church to commemorate the Battle of Britain. The Fees Office rejected his claim. Cook said that he had made the claim by mistake after reimbursing his assistant, and subsequently sued the newspaper for libel. He lost the case when the Telegraph submitted a defence of fair comment and Cook was unable to prove malice.
Personal life
Cook married Patricia Lundrigan in 1959; the couple had three daughters and a son. He was still married to first wife Patricia when he met Princess Somsangouane Baldinger of Laos at the 1992 Billingham folklore festival. He and Lundrigan divorced, and he remarried to Baldinger. In an interview in 2008, with the Evening Gazette, he said his new love was "almost too perfect". “She's a wonderful artist and a lady of considerable skill and merit... Do you know, she’s never made me the same meal twice since we met.”
Death
Cook was diagnosed with lung cancer in early 2011 and died, aged 76, at North Tees Hospital, Stockton on 10 January 2012.
