Counting has begun across the UK after millions of people cast their vote in the election to choose the government.
Polls closed at 10pm on Thursday, with Tony Blair hoping for an historic third term as a Labour Prime Minister.
Some constituencies race to be quickest with a result, with Sunderland South declaring first for Labour.
Even though voting started early, the first results won't come through until late on Thursday, so we won't know who's won until Friday morning.
Parties have been out and about on the election trail for the last 30 days, trying to convince people to vote for them.
At the last election in 2001, only 59% of adults voted, so experts will be on the lookout to see if this goes up or down.
Polling stations - where people go to vote - have been set up around the country. Many of them are in schools or village halls.
But some are in very unusual places - like caravans, pubs and even a bedroom.
