Wes Streeting has said the NHS is “addicted to overspending” as he launched an attack on health bosses.

He said those in charge of the healthcare system assume “someone will come along to bail them out” when they blow their budgets.

His comments come as he suggested hundreds more government quangos could be axed following the abolition of NHS England.

Appearing on Sky News this morning, Streeting was asked by presenter Trevor Phillips: “Is it right that Jim Mackey, the head of NHS England, has written to local health boards demanding that they produce plans for a 50% reduction in their spending?”

Confirming the move, Streeting said there would be a “particular focus on management costs” to achieve that target.

He said: “Myself and Jim are confronting a financial planning round for the year ahead where systems returned financial plans to us that would have involved an overspend between £5 and £6 billion before the new financial year has even begun.

“I’m afraid this speaks to the culture that I identified before the general election where the NHS is addicted to overspending, is addicted to running up routine deficits, with the assumption that someone will come along to bail them out, in a way that, by the way, local councils would never be able to do.”

Phillips replied: “Are you saying that the apparatus of the NHS was basically wasting public money?”

Streeting said: “I think there’s definitely examples of waste and duplication and we’re going to go hard at it.

“Even if the public finances weren’t tight - and they are - I don’t think even in the good times it’s acceptable that taxpayers’ money is wasted, because the money you’re wasting could be spent on other public priorities or could be put back in the pockets of taxpayers.”

Writing in the Sunday Telegraph, Streeting said he was committed to “slashing bloated bureaucracy”, suggesting many more health quangos could be axed.

“The abolition of NHS England – the world’s largest quango – is the beginning, not the end,” he said.

On the BBC’s Sunday with Laura Kuenssberg, the health secretary admitted the effeiciency drive will see “significant” numbers of NHS workers lose their jobs.

He said: “I’m going after the bureaucracy, not the people who work in it.

“Of course, I can’t sugar coat the fact that there will be a significant number of job losses and we will want to make sure we are treating people fairly, supporting them properly through that process. And I’m not criticising them, but I’ve got to make sure the system is well set up.”
