The government’s proposed changes to the controversial health reforms will be sent back to a committee of MPs next week.

MPs will debate a motion to recommit parts of the Health and Social Care Bill on 21 June following the u-turn on the proposals announced this week.

But Labour said it was “completely unacceptable” that the entire legislation was not being sent back to a committee for detailed scrutiny.

Shadow Commons leader Hilary Benn said the bill needed re-examining because the government had “messed it up first time round” and warned of further hold-ups in the House of Lords unless MPs were given the opportunity to do a thorough job.

Mr Benn said: “This is completely unacceptable and it will only make life more difficult for the government in the other place where, as we already know, it already has problems with time.”

He added: “The reason why this bill is in chaos is because the government really messed it up first time round.

“That’s why trust is in very short supply, and it therefore is essential for the House and all of those who care about the health service, that they have the time and the scope they need to look again, in detail, this time round.”

He added: “While no one wants to take responsibility for the mess, everyone is trying to take credit for the changes.”

Playing on tensions in the government, Mr Benn said the Liberal Democrats “think they have saved the NHS from the Tories”, irritating their coalition partners, while David Cameron “thinks he has saved the NHS from his health secretary, which no doubt makes him pretty cross too”.

The public have realised “you can’t trust the Tories on the NHS”, he said.

Commons leader Sir George Young, who announced the debate on sending parts of the bill back to committee in a statement to MPs, said former Labour health minister Lord Darzi had welcomed the change in policy.

Sir George quoted the peer as saying: “I certainly don’t see it as a u-turn, I see it as a continuum of reform.”
