As the dust settles in Downing Street after a day of ministerial shuffling, Boris Johnson has organised the youngest cabinet in the post-war era. And in a crucial year for Brexit negotiations, the prime minister has kept a strong representation of Leavers at the table. The shock announcement of the day was 39-year-old Rishi Sunak taking up the reins at 11 Downing Street, replacing Sajid Javid as Chancellor of the Exchequer. Mr Javid resigned his post after being offered the job, only on condition he sacked his team of special advisers. Esther McVey was the tenth housing minister to leave the office in as many years. Other moves included former International Development Secretary Alok Sharma replacing Andrea Leadsom as business secretary. His role has been taken by former junior defence minister Anne-Marie Trevelyan. Geoffrey Cox was sacked as Attorney General, to be replaced by former chair of the European Research Group Suella Braverman, while Theresa Villiers departed as Environment Secretary to make way for George Eustice, former farming minister and UKIP candidate. Oliver Dowden was promoted from a minister in the cabinet office to culture secretary. Steve Barclay, former Brexit secretary, was appointed Chief Secretary to the Treasury. A quarter of cabinet are women In his first cabinet eight of Mr Johnson"s 33 cabinet members were female - some 24.2 per cent. That figure has risen despite the departures of senior figures including Theresa Villiers, Andrea Leadsom and Esther McVey, to 25.8 per cent. It is after the Conservative Party as a whole returned record numbers of women to Parliament in the December 2019 election, with 87 female MPs (23.8 per cent). Under Mrs May, 31 per cent of the cabinet was female, slightly down on a high of 34.5 per cent after the January 2018 reshuffle, according to the Institute for Government. This was a higher percentage than at any other point in British political history, apart from a period of just over eight months under Gordon Brown (at 36 per cent). Youngest cabinet since 1945 The average age of Mr Johnson"s first cabinet was 47.7 years old, down from 51.2 under Mrs May. Thanks to the addition of 39-year-old Suella Braverman and the departure of 59-year-old Geoffrey Cox as the oldest member of the previous cabinet, the average age is now 47.4 years old. The youngest are 38-year-old housing secretary Robert Jenrick and 39-year-old chancellor Rishi Sunak. Aged 55, Mr Johnson is now the third oldest member of the cabinet, behind 56-year-olds Alister Jack and Simon Hart. Boris Johnson’s cabinet is the youngest since Clement Atlee, when the Democratic Audit began analysing the figures. The youngest before Boris Johnson became PM was Gordon Brown’s cabinet, which had an average age of 49 years old. The most privately educated ministers since John Major 21 of Mr Johnson"s 31 cabinet ministers were privately educated, some 67 per cent. This compares to 30 per cent of Theresa May’s 2016 cabinet, and represents a rise of three percentage points on the previous Johnson cabinet. According to data from the Sutton Trust, Mr Johnson’s rate of three in five cabinet ministers being privately educated is in line with all other recent Conservative Prime Ministers except Mrs May. 50 per cent of David Cameron’s 2015 cabinet, and 62 per cent of the 2010 coalition cabinet, received a private education. John Major saw 71 per cent of his 1992 privately educated, while the rate was as high as 91 per cent under Margaret Thatcher. The rate of privately-educated cabinet ministers stood at just 32 per cent under Tony Blair and Gordon Brown. Ethnic minority representation falls Mr Johnson’s cabinet has five non-white members, including Priti Patel and Rishi Sunak in two of the greatest offices of state. With the departure of Sajid Javid and promotion of Suella Braverman to a top job, the proportion of ethnic minorities has remained relatively stable. But after Amanda Milling replaced James Cleverley as party chairman, the proportion of ethnic minorities has fallen to 16.1 per cent from an historic high of 18.2 per cent last year. Four ministers at cabinet now have family backgrounds hailing from India. 84.8 per cent of Mr Johnson"s cabinet are now white, up from 82.2 per cent in his previous cabinet and lower than the national rate of 86 per cent. The Labour years didn’t see Blair or Brown have more than one minority ethnic cabinet member at any point. It took until 2002 for a Government to appoint its first mixed race member of cabinet - that was Paul Boateng when appointed Chief Secretary to the Treasury. Brexit-backers hold firm After Mr Johnson stuffed his cabinet full of Brexit believers last year, his latest reshuffle has cemented their place at the table. 43.8 per cent of the 2019 cabinet - 14 out of 33 ministers - backed Brexit in the 2016 referendum. After the latest reshuffle 45.2 per cent of the cabinet backed Leave in 2016 - 14 of the 31 ministers. It is thanks to the promotions of Penny Mordaunt, George Eustice, and Steve Barclay, among others. It was up from six out of 29 (20.7 per cent) in Mrs May’s government, although the former Prime Minister did suffer a raft of resignations from Brexit supporters, including Boris Johnson, Dominic Raab and David Davis.
