Education Secretary Gavin Williamson has claimed he has "forgotten" what his A-level results were.
As hundreds of thousands of pupils received their exam results, Mr Williamson appeared to suffer a memory lapse over his own grades.
The top Tory described his "absolute delight" on finding out his results 27 years ago - but refused to shed any light on what his results were.
"I didn't get three A*s, it's fair to say," he told LBC.
"I have forgotten, it is so long ago. It is 27 years ago.
"You probably can't remember what was happening last weekend."

Mr Williamson described his "absolute delight" at getting his results at his sixth form college in Scarborough, which allowed him to go to university.
He said he realised "all my dreams of doing social science at Bradford University" had been achieved.
"For a lad growing up in Scarborough, Bradford was the most exotic and exciting place in the whole world," he said.
"It opened up the pathway to those next steps and I was absolutely delighted."
Top politicians often keep their own A-Level results close to their chests.
Ex-Labour leader Jeremy Corbyn revealed that he had received two E grades at A-Level, while Ed Miliband was said to have got two As and two Bs in his exams.
Former Tory PM David Cameron was awarded three As in his A-Levels before going on to study at Oxford.
It comes as the number of students getting top grades hit a record high, with more than two in five (44.8%) pupils awarded an A or A* grade this summer.
