Andy Burnham is due to say in his speech today:
Labour publishes new analysis today which shows that NHS forced privatisation is entering new territory and becoming harder to reverse.
Contracts are being signed that will run for the five years of the next Parliament, and beyond. This is not acceptable. Contracts like this will tie the hands of the next Government in a crucial area of public policy.
But, even worse, they are being signed without a mandate from the public. The Prime Minister was not up front about these plans at the last election.
He needs to be reminded that he has never been given the permission of the public to put the NHS up for sale in this way.
