Democratic Senator Raphael Warnock has defeated Republican challenger Herschel Walker in Georgia's runoff election, to secure the Democrats an outright majority in the Senate for the rest of US President Joe Biden's term.
With Senator Warnock's second runoff victory in as many years, Democrats will have a 51-49 Senate majority.
There will be divided government, however, with Republicans having narrowly flipped control in the House of Representatives.
