“It’s going to get worse before it gets better.”

Prime Minister Sir Keir Starmer is expected to warn that things “are going to get worse” in the UK before they get better.

In his speech on Tuesday, the Prime Minister is expected to say there are no quick solutions to repair the “rubbish and ruins” left behind by the Conservative government.

He will also continue to claim that the previous administration concealed the true state of the state’s finances.

But the Conservatives have accused Labour of “inventing” a fiscal black hole to pave the way for tax rises and have called on Chancellor Starmer to reverse winter fuel cuts, saying they will leave pensioners “out in the cold”.

With just a week to go before Parliament returns from its shortened summer recess, the Prime Minister is expected to step up his attacks on the Conservative government in his speech.

He would say: “We have inherited not only an economic black hole, but a social black hole. That is why we have to act and do things differently.”

“Part of it is being honest with people about the choices we face and how tough they’re going to be.”

“Frankly, things are going to get worse before they get better.”

Since coming to power in July, Labour has highlighted the challenges facing its government and criticised Conservative ministers for failing to address them before the election.

Finance Minister Rachel Reeves began to address the theme in her statement before the summer recess, accusing the Conservatives of leaving a £22 billion surplus in this year’s budget.

“The Office for Budget Responsibility (OBR) was not aware of this,” he is expected to say.

“They wrote a letter saying that. They didn’t know, because the previous administration hid it from them.”

Kiir also addressed the wider public sector situation, saying those who took part in the recent violence had been able to exploit “cracks in society left by 14 years of populism and failure”, such as prison capacity shortages.

The Prime Minister is expected to insist change will not happen “overnight” and say Labour has achieved “more in seven weeks than the last government did in seven years”.

He will cite examples such as the creation of a National Wealth Fund, changing planning policy to build more houses and ending public sector strikes.

Sir Keir’s speech came ahead of what is likely to be a tough period for the Government as it prepares its first Budget, due on October 30.

Mr Reeves faces the challenge of delivering on Labor’s promises on tax and spending at a time when he has already said the public finances are weaker than expected, increasing the likelihood of tax increases.

Cabinet Office minister Pat McFadden told BBC Breakfast that the prime minister would show “refreshing candor” with the nation in his address, and said: “We will get there, but it will take time.”

He said the move to start means-testing the winter fuel allowance for pensioners was “not the decision we were hoping for”.

But Mr McFadded added: “When we came into power we found billions of pounds of unfunded spending and we had to make some very difficult decisions.”

He said there were around 900,000 pensioners who were eligible for pension relief but had not currently applied, and all pensioners should be confident that the pensions triple lock would be protected for the duration of Parliament’s term.

Responding to details of the Prime Minister’s speech, Conservative leader Richard Fuller said: “A weak Labour Chancellor is creating a fiscal black hole to trick people into accepting tax rises, wasting money while literally leaving pensioners behind.”

“The Prime Minister should either instruct the Finance Minister to reverse course or step in himself and reverse the decision.”

Limiting winter fuel payments to only those on pension credit and other means-tested benefits has also been criticised by former Labour cabinet minister Alan Johnson.

Mr Johnson, a former work and pensions secretary in the previous Labour government, told BBC’s World This Weekend that the Government should consider supporting pensioners who are not in receipt of means-tested payments but still on low incomes.

“For people just above the pension threshold, we need to consider a gradual reduction in benefits if we switch from universal to means-tested benefits,” he said.

“We need to look at how it will affect people just above the means-tested income threshold.”
