The Evening Standard reports:
Andrew Dismore is considering lodging an official petition after losing his Hendon seat by just 106 votes to Tory Matthew Offord.
He claims hundreds of would-be voters were prevented from casting their ballot because of failures by Barnet council to organise the election properly.
Mr Dismore, who has held the seat since 1997, claimed procedural and administrative errors by the council included: people queuing at 9pm being told to leave as they would not get in to vote in time; postal votes arriving late or not being sent, and wrong directions to polling stations being given.
