Announced in the last hour. A-level students in England are now being promised their final results will not be lower than their mock exams. The Department for Education is announcing a "triple lock" - so results will be the highest out of their estimated grades, their mocks and a back-up written exam in the autumn. It follows Scotland's decision to switch to teachers' predicted grades. England's Education Secretary Gavin Williamson said this would be a "safety net" for students.
