After leaving school in 1997, she decided against going to a university, and instead tried a series of different jobs, in journalism, investment banking, publishing, public relations, and stockbroking. In 1998, she moved with her family to Mells, Somerset. In 2003 she set up Trust the People, a campaign for a referendum on the European Constitution aimed at those too young to have voted in the Common Market referendum of 1975. Speaking about the 2003 Iraq War, she subsequently said, "I think it was a terrible mistake". She opposed the Hunting Act 2004. In the 2005 general election Rees-Mogg came fourth in the safe Labour seat of Aberavon, South Wales, increasing the Conservative vote from 2,096 to 3,064. She was selected as prospective parliamentary candidate for Somerton and Frome in 2006. The Observer said of her, "Having enjoyed finance and journalism, she combined the two in a career as a financial journalist. When she turns to discussing Gordon Brown's economic record, she does so with authority." In November 2007, she wrote an article for MoneyWeek magazine entitled "How to profit from the world's water crisis", setting out some of the investment opportunities in the sector. An article in The Sunday Telegraph in October 2009 reported, "Some high-profile women are already installed in winnable seats: Louise Bagshawe , Annunziata Rees-Mogg, Priti Patel, Laura Sandys and Joanne Cash will all make colourful additions to the Tory benches." However, at the 2010 general election, Rees-Mogg failed to take the Somerton and Frome seat from the sitting Liberal Democrat member David Heath. It was reported that in advance of the 2010 election David Cameron had asked Rees-Mogg to shorten her name for political purposes to Nancy Mogg, which her brother Jacob has since said was "a joke". Rees-Mogg later commented: "I think it's phoney to pretend to be someone you're not." Cameron subsequently dropped her from the Conservative Party's 2011 pre-selections, despite strong support from many female party members. On 12 April 2019, she was selected as a candidate for the Brexit Party in the East Midlands constituency in the European Parliament elections, and she won a seat. She resigned the party whip in December 2019 to support the Conservative Party's Brexit strategy. She later rejoined the Conservative Party in January 2020.
Personal life
In September 2010, Rees-Mogg became engaged to Matthew Glanville, and on 6 November 2010 they were married in Italy at Lucca. Four months later, on 8 March 2011, she gave birth to a daughter, Isadora, who was christened in St Martin's Church, Welton le Marsh in Lincolnshire. In 2018 she gave birth to a second daughter, Molly. In late 2019, she announced she was expecting her third child.
