LARRY Sanders called on Theresa May not to 'let the NHS and social care crumble' as tens of thousands rally in London today.

The East Oxford resident, whose brother Bernie Sanders was Hillary Clinton's main rival in the Democratic candidate race, will joined the crowds of people marching through London to Defend the NHS.

The demonstration was expected to be one of the biggest the capital has seen and protests against privatisation and cuts to NHS services.

Larry Sanders, health spokesman for the Green Party, addressed the crowd.

In his speech he said: "I have one eye on the disasters in America - and one eye on the disasters here. My brother Bernie is currently going to meetings in America just like this one, because of what Trump is trying to do to that country. Here, in my second home, my eye is on what is being done to the NHS.

"The NHS is an amazing organisation, built by people who knew that our society is richer when no one is left to the perils of a market in healthcare. But it is being undermined by the Conservative Government’s creeping privatisation of the NHS, and its devastating cuts.

"The NHS facing a £22 billion funding black hole. Adult social care is in financial crisis. Our ability to care for people in their time of greatest need is being eroded. If Theresa May wants keep her promise to ‘work for all, not just the privileged few’, she must not let the NHS and social care crumble on her watch."

Members of Oxford Labour Party have also travelled to the capital to join the rally.

Crowds gathered in Tavistock Square, London, before heading off on the march through the capital at 1pm.

Organisers have described the national demonstration as a rallying call to save the health service as "more austerity in the NHS represents a real risk to the safety of patients and the service".

The demonstrators began the march to the sound of pounding drums, blaring whistles and by chanting "Jeremy Hunt, we are here to say, our NHS is here to stay".

Junior doctor and GP trainee Dr Jeeves Wijesuriya believes the demonstration is a chance for the Government to plot a new course for the NHS.

Speaking on behalf of the BMA, he said the NHS "in reality faces £26 billion of health and social care cuts due to political decisions".

He told the crowd: "What is sustainable about debts that can only be paid with our patients' health and yet still won't be settled?

"Where is the transformation when the money to build new hospitals and health centres is being siphoned off to pay debts?"
