When will we know the US midterms results?

Congress is made up of two parts - the lower chamber, the House of Representatives and the upper chamber, the Senate.

To win a majority in the House, a party needs 218 seats. In the Senate, a party needs 51 seats for an outright majority. But if the upper chamber is split 50-50, the vice-president has a tie-breaking vote, which gives their party control of it.

First results will start to come in after 18:00 EST (23:00 GMT). They won't tell us much about the overall result because these races are in places considered safe bets for Republicans (Kentucky and Indiana) or Democrats (Vermont).
