At the close of voting (2200 BST) the ballot boxes were sealed and returned to the counting centres, where counting proceeded under the supervision of the returning officer who was obliged to declare the result as soon as it was known. As previously, there was serious competition amongst constituencies to be first to declare. Sunderland South repeated its performance in the last three elections and declared Labour incumbent Chris Mullin re-elected as MP with a majority of 11,059 at approximately 2245 BST (failing by two minutes to beat its previous best, but making it eligible for entry into the Guinness Book of World Records as longest consecutive delivery of first results). The vote itself represented a swing (in a safe Labour seat, in a safe Labour region) of about 4% to the Conservatives and 4.5% to the Liberal Democrats, somewhat below the prediction of BBC/ITV exit polls published shortly after 2200 BST.
