Republicans have clinched a dramatic and unexpected victory in the battle for control of the Senate, riding on the back of a stunning electoral upset in favour of Donald Trump.
Democratic hopes of retaking the Senate began to fade as its candidates failed to topple Republican incumbents in key states where victory had been anticipated.
The surprise outcome, along with the Republican hold on the House of Representatives, hands huge power to the incoming President Trump with implications for years to come.
It is the first time that Republicans have held the White House, the House and the Senate since 1928. That is also the last time the party won the presidency without a Bush or a Nixon on the ticket.
It gives Republicans full control.
