GCSE results - live: Exam chaos continues as hundreds of thousands of pupils won't receive grades despite Gavin Williamson being warned of algorithm problems 'weeks ago'

Hundreds of thousands of students in England, Wales and Northern Ireland are receiving their GCSE results on Thursday morning.

Teenagers across those countries will be awarded their final results, the higher of either their teachers' estimated grade or the moderated grade, after exams were cancelled.

It follows a government U-turn, with the announcement that GCSE and A-level students would be able to receive grades based on assessments by schools or colleges, rather than an algorithm, after thousands of A-level results were downgraded last week.

Meanwhile, Btec pupils will have to wait for their grades amid last-minute changes.

Btec grades were not included in the original government U-turn, but on Wednesday - with just hours to go until results day - Pearson said it would regrade Btecs to "address concerns about unfairness".

The exam board told schools and colleges not to publish level 1 and 2 results in the vocational qualifications on Thursday to give them more time to recalculate the grades.
