Democrats gain crucial Senate seat in fierce battle for Congress

BBC Summary

The battle for control of the US Senate is on a knife-edge with Democrats projected to win in the key state of Pennsylvania.

Democrat John Fetterman beat Republican Mehmet Oz, declaring "we held the line".

Control of Congress hangs on the results of tight senate races in the states of Georgia, Arizona and Nevada - so far yet to be called.

Democrat Maggie Hassan has fended off a tough challenge for her senate seat in New Hampshire while Republican JD Vance has won in Ohio.

Meanwhile Republicans are likely to take control of the House of Representatives, according to race projections.

The loss by the Democrats of either the House or the Senate will enable the Republicans to block President Joe Biden's agenda.

In high-profile contests for governors' seats, Republican Brian Kemp has defeated Democrat Stacy Abrams in Georgia and Republican Ron DeSantis has won in Florida.
