US election 2016: Cruz wins Wisconsin in blow to Trump

The US Republican presidential candidate, Ted Cruz has decisively won the Wisconsin primary, complicating front-runner Donald Trump's path to the nomination.  

In the Democratic race, Bernie Sanders scored a strong victory over Hillary Clinton in the Midwestern state.  

Mr Trump leads the Republican race, but there are concerns that he could fall short of the number of delegates needed to secure the party's nomination.  

Mr Trump's rivals have pinned their hopes on a contested convention, as party leaders, not voters, would choose the nominee in that instance.
