Trump moves closer to Republican nomination with string of victories

Donald Trump won a string of Republican presidential contests on Saturday, edging closer to becoming the party's candidate in November's election as he attacked his likely opponent Joe Biden.

The former president won the Missouri, Michigan and Idaho caucuses comprehensively, continuing his clean sweep of states so far.

Mr Trump, 77, told supporters at a rally in Virginia that he was "on a rocket to the Republican nomination".

He is on track to secure it next week.

His last remaining rival in the race, former South Carolina Governor Nikki Haley, is still seeking her first victory and is without a clear path to the nomination given Mr Trump's commanding lead.
