It's the morning after the night before, and with Ed Miliband's triumphant return to Feltham and Heston with winning Labour candidate Seema Malhotra, we thought we'd look at some of the reaction.
Labour polled 12,639 votes, and Malhotra benefited from a 8.6% swing to Labour.
Miliband said the result was a "verdict on this Government’s failing economic plan". "This is not just a swing from the Tories to Labour. It is a swing away from Tory ideas to Labour ideas. Labour ideas that put young people back to work. Labour ideas that gets growth going in the economy. Labour ideas that even in tough times, there can be hope."
With Simon Hughes and Baroness Warsi both saying they weren't surprised at Labour holding the seat, perhaps the most interesting hint is that the Conservatives will be coming for this sort of constituency in the future.
"Feltham and Heston are the kind of seats that we will be winning back", she told Sky News on Friday morning
