Washington: Real estate mogul Donald Trump today swept the crucial Florida Republican primary which will provide a major impetus to his aspiration to become the US President while Democrat Hillary Clinton won two key states.

The former Secretary of State was projected to bag at least 56 delegates out of 107 at stake in North Carolina. Clinton also won in Florida after having a massive lead over her sole rival Senator Bernie Sanders. Clinton had support of 65.6 per cent of the votes as against 30.6 per cent for Sanders.
