The action started around 1pm with people blocking the bridge by lying down, many dressed as health workers. Two massive banners stretched across the bridge, one suspended from bamboo tripods reading "Save Our NHS" and "Block the Bill". 

The blockade dissolved just after 4.30pm, following which a group of around 70 people were kettled by police on Lambeth Bridge. 

During the action and the occupy london assembly many people were also talking about the student protests planned for 9th November and the strikes on 30th November.

Jan 30th: UKuncut Shut Ox St Boots in NHS cuts action
Boots on Oxford street was shut down by protesters campaigning against cuts on Sunday 30th January. The Ukuncut protest was part of a nationwide series of around 30 actions. Hundreds of leaflets were handed out to passers by with many engaging in discussions about the cuts: "The Tories and Lib Dems are lying to us when they say these brutal cuts are based on necessity. The truth is that they are a political choice. They choose to cut vital public services and they choose to protect the interests of super-rich individuals and corporations, allowing them to dodge £25bn tax every year. The governments cuts are not 'fair', we're 'not all in this together', and there are alternatives."

May 17th: March to save the NHS
Following a call to "march for the NHS" around 1500 demonstrated on Tuesday 17th from Euston to Whitehall to protest the planned cuts for the NHS. The NHS bill currently pushed through by the Government will ultimatelly allow neoliberal capitalist thinking and its belief in the markets to dictate the type of services the NHS will provide, causing irreparable damage to it.
