Hundreds of students were turned away as polls closed at 10pm, because the station, at St John’s Church, Ranmoor was unable to cope with demand.
According to the University of Sheffield’s outgoing finance officer, Martin Bailey, police “forcibly removed the ballot boxes” shortly before 11pm.John Mothersole, returning officer for the Sheffield Hallam constituency, said: “We got this wrong and I would like to apologise.
“We were faced with a difficult situation with the numbers of people, and a large amount of students turning up to vote without polling cards. This made the administration process of ensuring the correct person was given a ballot paper much longer.
“The only remedy, which we could not take, was to extend the voting times.”
