Iowa caucus: Republican rivals make last-ditch bids to cut Trump's lead | BBC News

Donald Trump and his Republican rivals are making last-ditch pitches to win support in Iowa, hours before voters in the state will kick-off the 2024 race for the White House.

All of the candidates have urged voters to brave the extreme cold, as temperatures are forecast to fall as low as -30C (-20F).

A resounding victory in Iowa would cement Mr Trump's frontrunner status.

His rivals, meanwhile, are seeking to establish themselves as the main alternative to the former president.
