In United States, 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 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. At a contested convention, party leaders, not voters, would choose the nominee.
Mr Cruz is unlikely to earn enough delegates to win the nomination outright, but Republican Party leaders have rallied around the Texas senator in hopes of wounding Mr Trump.
On the Democratic side, Wisconsin adds to a recent spate of wins by the Bernie Sanders campaign, giving the Vermont senator a boost before key races in New York and Pennsylvania.
Mr Sanders won nearly every county in the state except Milwaukee, but as delegates are awarded proportionally he will not gain a significant advantage over Mrs Clinton.
Mrs Clinton still holds a sizeable lead and most analysts say she will eventually become the Democratic nominee despite her recent losses.
