The Chief Executive of Barnet council, Andrew Travers, has left his position by "mutual agreement", officials have confirmed.
Mr Travers leaves after a blunder with the electoral registrations left many voters unable to cast their ballot last Thursday.
All 155 polling stations in Barnet were affected.
A formal complaint over the problems had been lodged with Barnet Council by one of the Mayoral candidates.
Following the events during the morning of Thursday's elections, it has been decided, by mutual agreement that Andrew Travers, Chief Executive, will leave the council. We thank him for his time with the Council and wish him the best for the future.
I have enjoyed my time at Barnet and I believe the changes we have put in place and the continued programme of growth and transformation will enable the borough to continue to thrive.
