50,000 joined a TUC march in Manchester on 29 September, in support of the NHS and against Tory government policies.
The biggest contingent was from the public services union Unison. Other unions, trades councils, and campaigns had contingents; there were some local Labour Party banners, and a Green Party contingent; there was also a group of some hundred with banners and placards against the badger cull.
At the rally at the end, Andy Burnham, the Labour front-bench spokesperson on health, got a cool reception when first introduced, but much applause when he promised that the next Labour government, in its first Queen's Speech, will repeal the Tories' Health and Social Care Act.
He also explicitly opposed the policy that NHS care can be done by "any qualified provider". He said nothing on whether a Labour government would roll back the damage already done by the Health and Social Care Act, whether it would lift the crippling PFI payment burden from hospitals, and whether it will reverse the Tories' £20 billion cuts in the NHS.
