When will we know the US midterm election results?

On Tuesday night, the United States – and many people around the world – will be following one of the country’s most closely contested midterm elections in recent years. All 435 seats in the US House of Representatives and 35 of the 100 Senate seats are up for grabs as Democrats hope to take control of both chambers from President Donald Trump’s Republican Party. The first results should be known on Tuesday after polls begin to close. Voting will end first in some jurisdictions on the East Coast at 6pm (23:00 GMT). Results will continue to come in throughout Tuesday evening, and some probably won’t be known until Wednesday or later in some races as more states finish voting and officials start releasing their vote counts.
