Donald Trump has become the US Republican presidential nominee in all but name after victory in Indiana forced rival Ted Cruz from the race.

Mr Trump, unpopular with many in his own party, now has a clear path to the 1,237 delegates needed to claim his party's crown.

That would mark a stunning victory for a businessman few took seriously when he launched his campaign last year.

Bernie Sanders has defeated Hillary Clinton in Indiana's Democratic race.

He trails Mrs Clinton in the all-important delegate count but after this victory he said the contest was still alive.

But analysts believe that in General Election will fight Trump and Clinton.
