The march – against government cuts to the NHS – starts in Tavistock Square at midday and ends with a rally outside Parliament. Speakers are expected to include Broadchurch actress Julie Hesmondhalgh, Labour Party leader Jeremy Corbyn, shadow chancellor John McDonnell and BMA junior doctor committee chairman Jeeves Wijesuriya.
