Brian Sedgemore was born in Exmouth, Devon, and with his two siblings was raised by his mother; his father, a stoker in the Royal Navy, died during active service in World War II. He attended Newtown Primary School in Newtown, Exeter, and Hele's School, Exeter, a grammar school. He did RAFnational service from 1956 to 1958. He read PPE at Corpus Christi College, Oxford, and graduated in 1962. While working as a Whitehall civil servant, he trained at night as a barrister specialising in Criminal Law at Middle Temple, London, being called to the bar in 1966. During the 1970s he and fellow barrister David Fingleton contributed pseudonymous articles on politics and the police and criminal justice system to the Private Eye column Justinian Forthemoney. He wrote a number of books including The Secret Constitution and a novel, Power Failure.
Initially, he was a member of the Campaign Group, but he left the faction when he reversed his hostility to the European Commission in the late 1980s. He was later one of only five Labour MPs to vote for the Third Reading of the Maastricht Treaty in 1993, defying his party Whip, which was to abstain.
Female Labour MPs
On 6 February 1998 in a controversial speech at the Tate Gallery he disparaged the 1997 intake of female Labour MPs as "Stepford Wives…who've had the chip inserted into their brain to keep them on message and who collectively put down women and children in the vote on lone parent benefits" — in the previous month benefits had been reduced for this group of women. In the 2001–5 parliament he was the fifth most frequent rebel on the Labour benches in divisions on government motions and the tenth most frequent rebel on motions put forward by his own party.
Defection
On 25 April 2005, when he was no longer an MP during the run-up to the 2005 general election, he announced he would be defecting to the Liberal Democrats, citing the invasion of Iraq of which he had been a long-term critic, university tuition fees and anti-terrorism laws as reasons for his defection and Blair's "scorn for liberal Britain". He made various comments about Tony Blair being a liar, Blair responded on a BBC live television broadcast saying "He was not present at any meeting I had with George Bush and I don't remember having any conversation on the issue with Brian Sedgemore". Lib Dem leaderCharles Kennedy called Sedgemore's defection "a pivotal moment" in the election campaign.
Personal life
He was an Honorary Associate of the National Secular Society and a Distinguished Supporter of the British Humanist Association. He married Audrey Reece, a fellow barrister, in 1964; they had a son. They divorced in 1985 and remarried in 2002. Sedgemore died in 2015 after a fall in hospital while recovering from kidney surgery.
