Democratic presidential candidate Joe Biden has steamrolled rival Bernie Sanders in primary elections in Florida, Illinois and Arizona.
Accelerating his momentum in the race, the former U.S. vice-president made a clean sweep in all three states.
Biden appealed for support directly to Sanders supporters.
With his hat-trick, Biden took another big stride towards becoming the Democratic candidate who will face President Donald Trump in November.
Biden won a smashing victory over Sanders in Florida, the biggest prize of the night with 219 delegates. The former vice-president won 62% of the vote and about 130 delegates. Sanders, with only 23%, took some 48 delegates, with the rest still to be distributed.
A Democratic candidate needs 1,991 delegates to clinch the nomination.
