The winner of the Tory leadership contest will be announced at lunchtime today as Liz Truss and Rishi Sunak finally discover which one of them will replace Boris Johnson in No 10.

The long-running battle to be the next prime minister will draw to a close at approximately 12.30pm, with Sir Graham Brady, the chairman of the 1922 Committee of Tory MPs, due to announce the winner at an event in central London.

The winner of the contest is then expected to deliver a short speech, with Ms Truss and Mr Sunak due to be told who has won ten minutes in advance.

Ms Truss is viewed as the overwhelming favourite in the leadership election and a victory for Mr Sunak would stun Westminster.

Once the announcement has been made, the winner will then spend the afternoon and evening finalising their choices for their Cabinet and wider ministerial roles before formally becoming PM tomorrow.

IFS: Truss economic plan will fuel inflation

Liz Truss’s plan to cut taxes to boost economic growth will further fuel inflation, Paul Johnson, director of the Institute for Fiscal Studies think tank, has warned.

“She’s clearly absolutely right that we’ve had dreadful growth over the last 15 years,” the senior economist told the BBC Radio 4 Today programme.

“The 'but' is that simply cutting taxes, cutting National Insurance contributions, for example, is not a strategy for growth.

“And it is clearly pumping a large amount of money into the economy on top of the £30 billion we’ve already had to support energy bills, on top of the presumably many, many 10s of billions additional that are going to come from that, and on top of what’s going to have to be more money for public services.

“Now put all of that together and that will lead to not just extremely high borrowing in the short run, but also additional inflationary pressure."

'I think it’s just been too long'

Sir Geoffrey Clifton-Brown, a senior Tory MP, has said future Conservative Party leadership contests should be shorter.

The treasurer of the 1922 Committee told the BBC Radio 4 Today programme: "Now as a result of how we see it’s gone, we will need to rethink if and when it should happen again. I would shorten the process of members in the country.

“There was no reason why it couldn’t have been shortened. We could have had more than one hustings a day. I think it’s just been too long.”

UK has been 'treading water' during contest

Philip Hammond, the Tory former chancellor, has said the result of the leadership contest is a foregone conclusion and he expects Liz Truss to beat Rishi Sunak.

Lord Hammond said he believed "everybody will be relieved" once the result has been announced and that will enable the Conservative Party and the nation to finally "move on" from Boris Johnson's premiership.

He told Times Radio the UK has effectively been "treading water" during what has been a "difficult period" as the contest has taken place.

'You can't legislate to change the laws of economics'

There have been plenty of people during the Tory leadership campaign who have argued the next government must challenge so-called "Treasury orthodoxy" when it comes to spending decisions.

The idea of doing things differently on the economy and departing from the status quo has been a prominent theme, particularly for Liz Truss's supporters. However, not everyone agrees that "Treasury orthodoxy" even really exists.

Philip Hammond, the former chancellor, said this morning that he believes when people use the term what they are actually doing is facing the "economic facts of life".

Lord Hammond said ministers "can't legislate to change the laws of economics" and he said Ms Truss "understands that very well".

The former Cabinet minister said that "if you try and confront the laws of economics you will come unstuck" as he urged the next government to work "with the grain" rather than going against it.

Lord Hammond: UK must be 'realistic' on energy bills

Philip Hammond, the Tory former chancellor, has warned that households must get used to higher energy bills.

Lord Hammond said the next government must take action to combat the short term "war effect" on energy prices but he stressed that people must be "realistic" that "energy prices are not going to go back to where they were 18 months ago".

He said that "this winter, the next six, nine months is going to be extremely difficult" and the UK must avoid a "wage/price spiral" where wages chase prices, leading to "entrenched inflation that we simply can't get rid of".

Lord Hammond said that if the nation can "hold our nerve" he believes that inflation will start to fall from the spring next year.

Next PM faces 'challenges on virtually every front'

Gavin Barwell, who was Theresa May's chief of staff in No 10, has warned the next PM will face "one of the most difficult inheritances of any prime minister in my lifetime".

In a lengthy Twitter thread posted this morning, Mr Barwell said that Mrs May had "inherited the huge Gordian knot of Brexit, but the rest of the policy environment was (relatively) benign".

But he said Liz Truss or Rishi Sunak will face "challenges on virtually every front" as he highlighted spiking energy bills for families and businesses, strikes, the NHS backlog and "how to keep the lights on this winter" as just some of the difficult problems which will be in the next PM's in-tray.

Lord Barwell said that "the new prime minister may want low taxes but events will make it hard". He said he wishes the winner of the leadership contest well but added he hoped "they are under no illusion about the scale of the challenge".

Economist open to serving on Liz Truss's council of economic advisers

Liz Truss is planning to set up a "council of economic advisers" if she becomes PM. That council would then help guide the next government's economic policy as it tries to avoid a recession and combat the cost-of-living crisis.

Gerard Lyons, an economist who has backed Ms Truss's economic plans, has been tipped for a role on the council.

Mr Lyons was asked this morning if he could be part of the advisory body and he told Times Radio that "clearly it is up to the prime minister who she choses to be on a council".

But he said he does believe the council would be useful to act as a "different body of opinion" to the Treasury on economic matters. He said "Treasury orthodoxy" has been a long-running problem and must be challenged.

Asked if he would be open to serving on the council if he is asked to do so, Mr Lyons said "of course" but he would "need to look at the detail".

'They could do a lot worse than U-turn'

Liz Truss is considering freezing energy bills for millions of households this winter if she wins the Conservative Party leadership race, the Telegraph understands (you can read the full story here).

Such a move would be welcomed by Labour which has already called for the cap on energy bills to be frozen.

Steve Reed, Labour's shadow justice secretary, said this morning that Ms Truss should have already set out in detail how she intends to help struggling families.

He told BBC Breakfast: “It’s extraordinary that one of them will walk into Downing Street today with no idea what they’re going to do to help people. Now Labour’s winning the battle of ideas here, Labour’s come up with a fully-costed plan.

“They could do a lot worse than U-turn on what they’ve said in refusing help to families and look at what we’ve proposed and adopt it, as they have many times this year."

Next Cabinet must be 'broadly based'

Mark Harper, the Tory former chief whip and a supporter of Rishi Sunak, has said the winner of the leadership contest must appoint a "broadly based Cabinet" in order to get through what promises to be a rocky period in British politics in the months ahead.

Mr Harper was told during an interview on Times Radio that some of Liz Truss's supporters have been highly critical of Mr Sunak and his record as chancellor.

Asked if he believes it will be hard to unite the Conservative Party after the contest, Mr Harper said: "We have a democratic process here, party members will have made a decision... it is important for all Conservatives to get behind the new prime minister."

Mr Harper said the key to unifying the Tories will be appointing a "broadly based Cabinet that covers all wings of the party".
