A second recount at a key Conservative target seat has been suspended because volunteers were too tired to carry on.
The returning officer at Harlow, Essex, stopped work shortly after 0600 BST on Friday, but staff will return for a further count on Saturday morning.
A Harlow Council spokesman said: "Due to the tiredness of the count staff a recount will now take place tomorrow."
Volunteers began work at Harlow Sports Centre at 2130 BST on Friday. The first ballot box arrived at 2220 BST.
The decision to stop the count and send the 80 volunteers home was taken by the returning officer after consultation with the council's legal advisor.
Labour won a 5,228 majority over the Conservatives in the constituency in 2001.
The seat is being defended by Bill Rammell, a parliamentary under-secretary at the Foreign Office.
