England booed by own fans as they beat Japan at Rugby World Cup

Joe Marchant reached out to dot down at the death to ensure England, who opened their World Cup campaign with a 27-10 victory over Argentina, took five points for the win.

"Tonight it was really tough, we got a bonus point so we're really pleased with that," said Borthwick, whose fly-half George Ford kicked 14 points to be named man-of-the-match for the second successive match.
