Prime Minister Theresa May has come under fire over claims she is planning to give the green light to a new wave of selective grammar schools.
Opposition parties reacted with fury to reports that selective education may be back on the agenda, vowing to fight a system which Labour spokeswoman Angela Rayner said should be placed "in the dustbin of history".
The Sunday Telegraph reported that the PM could announce she is lifting the ban on new grammar schools as early as the October Conservative conference.
Downing Street did not deny the report, but said only that any change in policy would be announced "in due course".
Any return to the grammar system can be expected to be divisive - critics argue that the 11-plus exam led to elite schools dominated by middle-class children while the majority of young people from poorer backgrounds received sub-standard education in secondary moderns.
People have been sharing their thoughts on the potential move online.
May is thought to be a supporter of new selective schools, having backed a grammar school's proposal to open a new "annexe" in her Maidenhead constituency. And the PM's new chief of staff Nick Timothy has also backed new selective schools in the past.
May's predecessor David Cameron annoyed some Conservative backbenchers by resisting the creation of new grammar schools, focusing his education policy instead on academies and free schools which do not select on ability at the age of 11.
