Thousands of people marched through London on Saturday demanding more government funding for Britain's National Health Service.

The state-funded health service has been under mounting pressure, with demand from a growing, aging population, rising faster than investment. Winter illnesses and an exodus of stress-hit medical staff, have led to thousands of cancelled operations, and long waits for ambulances and emergency treatment. Both trade unions and the main opposition Labour Party, backed Saturday's protest. The British government says they are putting more money into health care, and training more doctors and nurses.
