*UPDATE* The first round of strikes in September have been suspended by the BMA, whose leaders have caved in to pressure from managers. The subsequent strikes set for October, November and December are still going ahead (so far).
Junior doctors will be on strike for five days from 12 September. This escalation comes out of a rejection by members of the deal put to them by the leadership of their union, the BMA.
Further action has already been announced for October, November and December.
