Judge Kavanaugh has vehemently denied the allegations made by Prof Christine Blasey Ford.

The US Senate has narrowly advanced President Donald Trump’s Supreme Court nominee Brett Kavanaugh’s nomination to a final vote.

Friday’s vote – 51-49 in favour – was a test of support for the embattled nominee who has faced sexual assault allegations from several women.

All eyes are on several swing senators for Saturday’s final vote.

Judge Kavanaugh’s confirmation would tilt America’s highest court in favour of conservatives.

The nine-member panel has the final say on issues such as abortion, gun control and voting rules and justices are appointed for life.

Following Friday’s vote, Mr Trump tweeted that he was “very proud”.

Hundreds of protesters against Judge Kavanaugh were arrested in Washington DC, on Thursday, including comedian Amy Schumer.

After Friday’s vote, dozens also were arrested outside Republican Senator Jeff Flake’s office. Mr Flake told reporters that unless “something big” changes, he will vote to confirm Judge Kavanaugh.

Friday’s “cloture” vote activated a 30-hour period of discussions in the Senate, which will be followed by the final simple majority vote on Saturday.

Republicans have a 51-49 majority in the Senate. But two key swing senators voted against their party colleagues: Republican Lisa Murkowski and Democrat Joe Manchin.

Mr Manchin, of West Virginia, represents a traditionally Republican state that Mr Trump won by a landslide. The self-described “most centrist Democrat” is also up for re-election this year.

Ms Murkowski of Alaska, a state that also voted pro-Trump in 2016, has been undecided on Judge Kavanaugh throughout the hearings.

She has been lobbied by sexual assault survivors to vote against the judge and represents a state with the highest sex crime rate by far in America, according to FBI data.

Despite deciding against the nominee on Friday, she told reporters afterwards she has still not made up her mind on the confirmation vote, according to Reuters news agency.

Another key Republican senator, Susan Collins, a moderate from Maine, announced that she would vote in favour of Judge Kavanaugh on Saturday.
