He went to Hereford High School for Boys, followed by Hereford Sixth Form College. Keetch joined the Liberal Party while still at school, and chaired the Hereford Young Liberals and the West Midlands Region Young Liberals, as well as being the election agent for the Liberals in Hereford in 1983. He was elected to Hereford City Council in 1983 at the age of 21, making him the then-youngest city councillor in the UK, and served two years before resigning to move to London. His first jobs were in banking and financial services, before moving to the water hygiene industry and Franklin Hodge self-assembly water tanks. He moved to London for Hodge in 1985, but soon left to become a self-employed public affairs consultant.
In 2008, The Daily Telegraph stated that Keetch "never knowingly underspent", and it mocked his "expense-fuelled forays to John Lewis", including "such indispensable items as a cheese grater, three large bottle stoppers and a white pudding basin." During the 2009 United Kingdom parliamentary expenses scandal, the Hereford Times noted that in the past year he had claimed £142,385, including £87,000 on staffing costs, and £23,351.74 in second home allowances. Keetch missed 9 out of 10 parliamentary votes on MPs' expenses. The Daily Telegraph recorded that his "mortgage jumped from £145,000 to £300,000 when he sold a flat in Stockwell in London last year and moved around the corner. The new flat was furnished with a sofa-bed costing £690 and a wardrobe at £624." In March 2010, a BBC investigation showed that Keetch had breached House of Commons rules relating to declaring outside interests. In 2005, he twice visited Gibraltar, firstly paid for by the Liberal Party of Gibraltar and secondly paid for by the Gibraltar government, yet when he asked two parliamentary questions and signed three Early Day Motions relating to Gibraltar, he failed to declare either of these interests. Similarly, he visited Korea in 2006 paid for by the government, but failed to declare this when he subsequently signed an Early Day Motion on Korea.
Personal life
Keetch married Claire Elizabeth Baker on 21 December 1991 and they had one son. She worked for her husband as a constituency case worker. They divorced in 2011. On 8 July 2007, he was taken seriously ill whilst travelling to the United States on a flight. The pilot turned the aeroplane back to London and he was admitted to London Chest Hospital. Doctors eventually diagnosed him with idiopathic ventricular fibrillation and fitted an implantable cardioverter-defibrillator. On 13 November 2009, The Sun printed front-page photos of the married MP kissing the estranged wife of SAS soldier and author Cameron Spence, with the pair staying overnight in Keetch's flat and subsequently emerging at 10:30am the next day, 11 November. Keetch's first wife divorced him just over a year later. In 2016, Keetch faced a police probe over allegations that he had texted a former lover that she had "12 hours to agree" to have sex with him, or he would post nude photographs of her online, and would kill her cats, allegedly vowing in the texts, "I’ll send you their ashes." The woman had previously shared a Clapham flat with Keetch. A colleague, Mark Pursey, noted that "by 2016 it was abundantly clear that was not a well man: he had fallen ill on a flight to Washington nearly ten years previously with heart problems; his personal affairs – into which he would occasionally, perhaps unintentionally, share glimpses – were evidently not as optimal as he would have liked."
Post-parliamentary career
After he stood down from parliament in 2010, Keetch resumed work as a lobbyist, initially working alone. In 2011 he became a founding partner in Wellington Street Partners with retired Conservative MP Sir Sydney Chapman and expelled Labour MP Phil Woolas. Keetch resigned from the partnership in 2013 and resumed independent practice. On 7 March 2016, Keetch announced he would be campaigning to leave the European Union in the 23 June EU referendum. He fronted the "Liberal Leave" organisation and was the only prominent Liberal Democrat to endorse a Leave vote. After a short illness, Keetch died on 24 May 2017, at the age of 56.
