Education Secretary Gavin Williamson has resisted calls to resign over his handling of A-level and GCSE grades in England, but he has apologised to thousands of students for the distress caused.

The Government announced a U-turn on Monday when it said students would be able to receive grades based on their teachers’ estimates following anger over the downgrading of thousands of A-level results.

But Mr Williamson has repeatedly refused to say whether he would consider resigning from his position.

The minister said there had been “broad political consensus” across all parties that a standardisation model was needed for teachers’ assessments of grades after exams were cancelled amid Covid-19.

Mr Williamson insisted that England’s exams regulator, Ofqual, “didn’t deliver” the grading system that the Government had been “reassured” would be in place.

Universities have called for urgent support from the Government to ensure A-level students do not miss out on their first-choice places.

Students who now have higher grades amid the U-turn – which came four days after A-level results were announced – could still be asked to defer their place if there is no space left on their preferred course.

Speaking on BBC Radio 4’s Today programme on Tuesday, the Education Secretary said: “I’d like to just start off by apologising, saying sorry to all those young people who have been affected by this.

“This is something that, firstly, none of us wanted to see and none of us expected to see.”

Tory MP and chairman of the Education Select Committee Robert Halfon called the situation a “mega-mess” after he had warned of the risk that disadvantaged pupils could be negatively affected.

Asked who is to blame for the problems in the exams system, the Conservative MP told ITV’s Good Morning Britain: “We need to find that out. I’d like to see the minutes of everything that has gone on.

“I also think we should find out how much this has cost the taxpayer just so that we make sure that this never happens again.”

Mr Halfon added: “What has happened has been a mega-mess and I really feel sorry for all the pupils and students and parents across the country who’ve had so much anguish over the past week through no fault of their own.”

Shadow universities minister Emma Hardy said Mr Williamson’s delay in allowing pupils to be given grades estimated by teachers has caused a “massive headache” for universities.

She told BBC Breakfast: “His delay in making this decision has meant that more and more places at university have been filled up.

“Many students have gone ahead and accepted their second-place offers or other offers, or in fact got offers that maybe in the past they wouldn’t have actually been entitled to.”

Asked whether she thinks Mr Williamson should resign, she said: “Well, I know if I was in charge of the Government he certainly wouldn’t be in my team, but that’s a matter for Boris Johnson.”

Meanwhile, Liberal Democrat leadership hopeful Layla Moran called for the Prime Minister to sack Mr Williamson and criticised the Education Secretary’s attempts to pass the buck on to Ofqual.

“There must be consequences for this catastrophic failure of governance,” she said. “Gavin Williamson must resign, and, if he refuses to go, Boris Johnson must sack him.”

Speaking on BBC Breakfast, Mr Williamson said: “What we’re doing is we’re focusing on delivering the grades for those children.

“We’re making sure that we’re going to make sure that all schools are returned and I’m absolutely determined over the coming year that I’m going to be delivering the world’s best education system.”

The Westminster Government’s U-turn in time for the GCSE results in England on Thursday brings the nation into line with Scotland, Wales and Northern Ireland, which will all use teacher-predicted grades.

Mr Johnson and Mr Williamson had previously defended the “robust” system, while the Education Secretary had insisted there would be “no U-turn, no change” and said a shift could lead to “rampant grade inflation”.

Ofqual chairman Roger Taylor admitted the regulator had gone down the “wrong road” and apologised.

The algorithm was meant to moderate the process of awarding grades, preventing teachers awarding what the exams watchdog described as “implausibly high” marks to pupils.

But it came under fire over its perceived unfairness and the way it particularly appeared to penalise bright children from disadvantaged schools.

Mr Williamson accepted that it had produced more “significant inconsistencies” than could be rectified through an appeals process, saying it became “apparent” to him that more action would need to be taken after Ofqual released additional data about its algorithm.

Mr Johnson, who is on holiday in Scotland, held crisis talks with Mr Williamson and senior officials on Monday morning to discuss the policy shift.

Students who were awarded a higher grade by the moderation process will be allowed to keep it, but for many pupils the shift to teachers’ predictions will see their grades improve.
