Rishi Sunak, and others, launch bids to replace Boris Johnson

We need a return to traditional Conservative economic values and not fairy tales, says Sunak

Ex-finance minister Rishi Sunak, the favourite to become Britain's next prime minister, kicked off his campaign on Tuesday promising "honesty", in an increasingly testy and divisive battle to succeed Boris Johnson.

An initial 11 candidates put their names forward to become the leader of the governing Conservative Party and Britain's next premier after Johnson was forced to say he would step down when support drained from him over a series of scandals.

Only those who get nominations from 20 of their 358 Conservative colleagues in parliament on Tuesday will go forward to the first vote on Wednesday. The field will then be quickly whittled down to a final two, with Conservative Party members making the final decision.

Transport minister Grant Shapps became the first to end his bid, throwing his support behind Sunak, whose resignation helped provoke the revolt by ministers and Conservative lawmakers that forced Johnson to say he would resign last week.

The new leader faces a busy in-tray as well as falling opinion poll support.

Britain's economy is facing rocketing inflation, high debt, and low growth, with people coping with the tightest squeeze on their finances in decades, all set against a backdrop of an energy crunch exacerbated by the war in Ukraine which has sent fuel prices soaring.

As the contest heated up, rival campaigns stepped up private criticism of each other and pointed to either financial or other questions hanging over their opponents.

With most candidates saying they would cut taxes if they win, Sunak, the current bookmakers' favourite, has sought to portray himself as the serious candidate, promising "grown-up" honesty "not fairy tales".

"It is not credible to promise lots more spending and lower taxes," said Sunak.

As finance minister, Sunak set Britain on course to have its biggest tax burden since the 1950s, and the other prime ministerial hopefuls have turned their fire on him on tax, with most saying they would oversee cuts immediately.

Sunak said he did not want to distance himself from the financial decisions he made during the Covid-19 pandemic.

"Whilst that may be politically inconvenient for me, it is also the truth. As is the fact that once we've gripped inflation, I will get the tax burden down," he said. "It is a question of when, not if."

'Sound Money'

The former finance minister has the widest support among colleagues who have publicly expressed their views, including the backing of Deputy Prime Minister Dominic Raab.

"I know that Rishi has got what it takes," Raab said, introducing Sunak at his campaign launch event.

Penny Mordaunt, a junior trade minister who is also heavily tipped, topped a poll of Conservative members on Monday and she too has tried to strike a more measured tone on tax, saying that while she would cut taxes: "I will pioneer sound money."

"I am a small state, low tax conservative, but I also believe we need to use the levers of government to support jobs and livelihoods through difficult economic situations," she wrote in the Daily Telegraph newspaper.

Among the others to launch their campaigns on Tuesday were Tom Tugendhat, the chair of the foreign affairs committee, and Kemi Badenoch, a former junior minister who is scooping up some support on the right-wing of the party.

Foreign Secretary Liz Truss was also hoping to challenge those at the top of the leader board and received the backing on Tuesday of two ministers closest to Johnson - Nadine Dorries and Jacob Rees-Mogg - who have both been critical of Sunak.

On Monday, the 1922 Committee of Conservative members of parliament agreed on the rules for the contest, saying the field will soon be whittled down with repeated votes in the next few weeks and the final two being presented to the party by July 21.

It said the winner, and Britain's new prime minister, would be announced on September 5.

The main opposition Labour Party will put forward a motion of no confidence in the government on Tuesday to try to force Johnson out of office straightaway. The vote will be held on Wednesday and although some Conservatives have voiced concern about Johnson remaining as prime minister, they are very unlikely to support it.

The new leader will have to reverse evaporating support. A survey by Savanta ComRes on Monday put Labour at 43 per cent compared with 28 per cent for the Conservatives, its biggest poll lead since 2013.
