Jeremy Hunt is expected to face a grilling in the Commons later today amid reports that relations between NHS bosses and Downing Street have soured.

It comes after Labour secured an all-day debate in Parliament, demanding that the embattled Health Secretary and Downing Street come up with a solution to the crisis in the NHS. Just last week the British Red Cross called the situation in NHS hospitals a “humanitarian crisis” – a claim the Government has rejected.

Mr Hunt’s appearance in the Commons also comes after reports in the Times of tensions between Downing Street and the chief executive of the NHS Simon Stevens. According to the newspaper senior aides had expressed irritation with his “unenthusiastic” approach.

Jonathan Ashworth, Labour’s shadow Health Secretary, said some patients in the health service have to wait hours – on trolleys and hospital corridors – in overcrowded A&E departments.

“At a time like this, the Government should be taking action to ensure the NHS is given extra resources to deal with the challenges it is facing,| he added.

“Unfortunately, all we’ve seen from the Government this week is a suggestion to water down the four hour A&E target.

Labour is calling on the Government to ensure that the NHS has proper funding, to guarantee that key waiting targets are protected and to abandon any attempts to downgrade the A&E target.”

On Wednesday the Royal College of Physicians (RCP) – representing more than 30,000 doctors across 30 specialities – added that vital NHS services are “struggling or failing to cope”.

RCP Registrar Andrew Goddard told The Independent the organisation’s members had expressed fears "that the whole system was collapsing, that there is a crisis”.

“Our hospitals are over-full, with too few qualified staff,” wrote RCP President Professor Jane Dacre in a letter to the Prime Minister signed by the prestigious body’s nearly 50 council members.
