There is perhaps only one leader whose physical greetings are talked more about than the "clasp and yank" handshake of Donald Trump.

India's Prime Minister Narendra Modi left Prince William's hand white after taking it in a vice-like grip last year and has become well-known for his vigorous hugs of other world leaders.

When they met at the White House on Monday, therefore, all eyes were on the greeting. Would it be a handshake or a hug?

In the end, Mr Modi swooped in for two big bear hugs with the US president during their joint statements in the Rose Garden.
