Prime Minister Liz Truss has held her first cabinet with her newly assembled top team this morning – before going head-to-head with Sir Keir Starmer at PMQs.

On Tuesday, in her first speech as prime minister, Ms Truss said the UK would “ride out the storm” caused by the war in Ukraine and promised a package of reforms to “transform Britain” including measures to boost growth and put the NHS on a “firm footing”.

She also pledged to tackle soaring energy bills as an immediate priority.

It has been reported that annual bills will be frozen at around £2,500 – more than £500 above the current price cap but £1,000 less than the limit due to be imposed in October.

Therese Coffey, the new health secretary and deputy prime minister, told Sky News that proposals will be set out to parliament this week.

However she refused to comment on whether the UK will borrow to fund energy help for consumers.

Asked whether the package to support households will be funded through general taxation or borrowing, Ms Coffey said: “Ultimately, we receive money through taxation from people and businesses and then redistribute that accordingly to the priorities set out in our manifesto and the needs of the country. So more will be said about that, aspects of that in during this week.”

Who are Liz Truss’s top three cabinet members?

She added: “People, including you, will just have to wait for the detail of that.”

Labour leader Sir Keir will likely probe Ms Truss on her prospective energy proposals at PMQs.

His party has called for the energy price cap to be frozen now, which would be paid for by introducing a new windfall tax on oil and gas companies’ profits without a “major tax loophole” it claims the government’s current windfall tax has.

After giving her speech outside Number 10, Ms Truss appointed her cabinet team who will gather for their first meeting this morning.

Supporters of leadership rival Rishi Sunak – including former justice secretary Dominic Raab, former transport secretary Grant Shapps and former health secretary Steve Barclay – were removed from their senior government positions.

Loyal allies of Ms Truss were rewarded for their long-term support, including Ms Coffey, a close friend who was promoted from work and pensions secretary to health secretary and deputy prime minister.

Ms Coffey was asked about the challenge of paying for health and social care without the guarantee of extra funds from the soon-to-be-canned national insurance hike.

She insisted the NHS would receive the same investment, but through general taxation.

She also reiterated her top four priorities: “A, B, C, D – ambulances, backlogs, care, doctors and dentists”.

Big promises from the new PM

Elsewhere, former business secretary Kwasi Kwarteng was elevated to chancellor – and Sky News understands in the first few hours of the job he summoned the bosses of Britain’s biggest banks for talks today.

On Wednesday, he tweeted a picture of the meeting, saying he had “set out the prime minister’s new, pro-growth economic approach”.

A press release after also said the government would “immediately focus on supporting families and businesses to navigate the gas crisis this winter and next”, which would mean “necessary higher borrowing in the short-term”.

But the Treasury insisted it would ensure “monetary stability and fiscal discipline over the medium term”, and that Mr Kwarteng was “committed to ensuring the economy grows faster than our debts and keeping debt as a proportion of our economy on a downward path”.

Former attorney general Suella Braverman was appointed home secretary following Priti Patel’s departure, while James Cleverly was promoted to the position of foreign secretary which Ms Truss had previously held.

Mr Cleverly had worked as a minister in the Foreign Office for two years, acting effectively as Ms Truss’s deputy.

Former minister of state for Brexit opportunities and government efficiency Jacob Rees-Mogg was promoted to business secretary, while Former Northern Ireland secretary Brandon Lewis’s loyalty to Ms Truss saw him awarded the justice brief.

Former chancellor of the Duchy of Lancaster and policing minister Kit Malthouse was given the education brief, while former international trade secretary Anne-Marie Trevelyan will deal with the autumn of planned railway strikes in her new role as transport secretary.

The PM’s press secretary said Ms Truss had appointed a cabinet “which represents the depth and breadth of talent in the Conservative Party” and which will “unify the party, get our economy growing and deliver for the British people”.

More junior ministers are expected to be appointed today.

Shortly after making her first address outside Downing Street, the new PM made her first call – as promised – to Ukrainian President Volodymyr Zelenskyy.

In a statement after they had spoken, Ms Truss said: “Ukraine can depend on the UK for support in the long term.”

Meanwhile, in a post on social media, President Zelenskyy said he thanked Ms Truss for the UK’s continued support for Ukraine and invited her to visit the country.

Ms Truss also spoke to US President Joe Biden.

President Biden offered his congratulations, saying he looked forward to “deepening the special relationship between our countries and working in close cooperation on global challenges, including continued support for Ukraine as it defends itself against Russian aggression”.

Ms Truss said she and Mr Biden discussed working together on shared challenges such as the economic impact of the war in Ukraine and promised to build on “UK-US links”.
