The result was in doubt until Rob Thirlby burst through a gap in the Pumas defence and outpaced the cover to cross deep in the second half.

In the Plate event,a moment of individual brilliance from Scotland's Kenny Sinclair helped his side to a 28-22 victory over France.

The Cook Islands proved too strong for Japan in the Bowl final to win 31-19.

The win gave England their third consecutive Hong Kong Sevens crown, and will ensure that they start as favourites to win next year's seven-a-side World Cup, which is to be staged in Hong Kong.

England coach Joe Lydon said the senior XV's defeat against France in the Six Nations on Saturday had served as a spur for his team.

"We wanted to make sure we were picking up the silverware today after what happened in Paris," said Lydon, referring to England's 24-21 defeat.

Lydon said he was not surprised to see Argentina in the final following the Pumas' shock 19-17 semi win over New Zealand.

"They're a quality side and they got into the final on merit. It wasn't a fluke on their part and we knew that we were going to have our work cut out," Lydon added.

Amor, who captained England, said the side had made light of the unavailability of star playmaker Henry Paul, ruled out of the tournament after an ugly club versus country row.

"Who's Henry Paul?" the diminutive scrum-half quipped.

"It was a great team effort. I can't really remember anything about the final except that we won."

And Scotland coach Rob Moffat praised his side's win in the Plate, saying: Coach Rob Moffat said: "The boys played well in what was a great team effort."
