A huge amount of data gathered over the six weeks of the campaign—144 national polls in all, surveying a total of 622,000 people—pointed to one outcome: a Labour landslide. That outcome duly materialised: Labour’s haul of 411 seats gives it a working majority of 181 in the new Parliament, which began on July 9th. Even so, the polling firms did not cover themselves in glory.
