Exam chief's 'profound regret' over A-level leaks
The head of one of England's biggest exam boards has expressed "profound regret" after leaks hit two of its A-level exams in the past few days.
Rod Bristow said Edexcel's maths and economics exams had been overshadowed by concerns that content had been available beforehand.
Some of an economics exam appeared on social media and a maths paper was apparently for sale online.
Police arrested and released two men pending further inquiries in the case.
The alleged leaks prompted angry responses from teachers' and head teachers' leaders, who said this year's exams had been "plagued" with problems.
