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.
