Despite efforts from health secretary Jeremy Hunt to allay fears over the potential impact of changes to junior doctor contracts, doctors' leaders remain concerned that the changes could bring cuts of up to 30% to GP trainee and junior doctors' pay.
Junior doctors are about to be balloted by the BMA over industrial action.
BMA education, training and workforce subcommittee chair Dr Krishna Kasaraneni, former RCGP chair Dr Clare Gerada and other senior GPs were among the protesters.

To enable junior doctors to take time out of work (on a Saturday) and take part in the protest, consultants were reported to have worked for free to provide cover.
