John Cridland, CBI Director-General, said: “We congratulate Sajid on his appointment as Business Secretary. He was an excellent Treasury Minister and will be a strong voice for the business community, helping to make its voice heard loud and clear at the Cabinet table.

“We want to encourage more companies, especially Britain’s forgotten army of medium-sized businesses, to boost exports and investment, to drive growth and create jobs up and down the country. We look forward to working with Sajid to achieve this."

Chris Bryce, chief executive of IPSE, the Association of Independent Professionals and the Self Employed, said: “The UK’s economic growth depends on the self-employed and small businesses having the right regulatory framework to thrive and we eagerly anticipate the new Business Secretary bringing forward an agenda that inspires confidence in the business community. One pillar of this will be conducting a root and branch review of the business rates system which currently holds back many self-employed people who frequently use work hubs."

Helping to boost the agenda of small businesses, Anna Soubry has been appointed Minister of State for Small Business.

John Whittingdale replaces Mr Javid as the Secretary of State for Culture, Media and Sport.

Intensifying speculation that Boris Johnson is being lined up to replace David Cameron as Conservative leader when he steps down, the Mayor of London will attend cabinet meetings, but not hold a ministerial role. He will continue as Mayor of London for this year.

Priti Patel has been appointed as Minister of State for Employment at the Department for Work and Pensions. Amber Rudd takes places as Secretary of State for Energy and Climate Change. Nicky Morgan has been appointed as Secretary of State for Education.

Reacting to the appointment of Amber Rudd as energy and climate change secretary, Paul Barwell, CEO of the Solar Trade Association, said: “We very much welcome Amber Rudd’s appointment as Secretary of State for Energy and Climate Change, and look forward to working with her to make sure solar reaches its full potential. We need stable policy support and strong leadership on solar - just one final push could get rooftop solar to zero subsidy by the time this Government leaves office.”

Mr Cameron had already reinstated George Osborne as Chancellor of the Exchequer, Theresa May as Home Secretary, Michael Fallon as Defence Secretary, Philip Hammond as Foreign Secretary. George Osborne has also been made the first Secretary of State and Michael Gove returns to the front bench as Justice Secretary.

Opposition reshuffle

Meanwhile, Labour, the Lib Dems and UKIP all start their searches for a new leader after their respective leaders resigned on Friday.

Ed Miliband, Nick Clegg and Nigel Farage all stepped down following the election results. Ed Miliband and Nick Clegg resigned primarily for their parties' failure at the polls, whereas Mr Farage promised to step down if he failed to win election in the Thanet South constituency. However, UKIP has now "unanimously rejected" his resignation following the "great success" of party's campaign.

Acting Labour leader Harriet Harman had a reshuffle of her own. Ms Harman appointed Chris Leslie as shadow chancellor, filling the seat vacated in dramatic fashion by Ed Balls who unexpectedly lost his seat during the general election.

Ian Murray, Labour's only Scottish MP, becomes the party's shadow Scottish secretary. Sadiq Khan has left his role in the shadow cabinet ahead of his bid to become Mayor of London.
