The Conservative party's chief strategist, Lynton Crosby, and his Australian colleague Mark Textor have tweeted this photo.
While results are still continuing to come in, the pair – who co-own the polling and strategy firm Crosby Textor – obviously feel happy enough about how things are going to start celebrating.
Crosby, who was the campaign manager for Boris Johnson's London mayoral campaign, was reportedly paid up to £500,000 to act as David Cameron's chief strategist.
The American campaign guru Jim Messina tweeted another celebratory photo. Messina, who was Obama's 2012 campaign manager, has been serving as a senior Conservative party adviser since 2013.
