The outcome of the US midterm elections may not be known immediately after polls close, with projections potentially taking several hours, days or even weeks.
The timing means that voters and observers may have to wait beyond the end of polling before results are declared or projected. Some contests could be called relatively quickly, while others may remain unresolved for a longer period.
No single timetable has been given for when the overall results will become clear. The latest position is that projections could continue over an extended period following the close of voting, leaving the final picture uncertain until the relevant results are assessed and announced.
