Five Harlequins youngsters have been included in the England U18s side in South Africa in July and August for a development tour.

Rob Buchanan, Charlie Matthews, Joe Trayfoot, Sam Twomey and Sam Stuart are in the 26-strong group, which will be looking to build on their clean sweep of wins in this season's Five Nations Festival.

England, who defeated Scotland twice, Japan High Schools, Italy and Wales this season play three matches in South Africa, against Western Province on August 1, Boland on August 4 and South Africa Schools on August 8.

England U18s head coach John Fletcher said: "Development tours like this are crucial to the progress of talented young players at this age.

"Although playing in the Five Nations Festival is hugely important, players also need to compete against the Southern Hemisphere teams as well.

"They are some of the strongest sides around and our players need to get used to travelling and touring as that is what happens in international rugby.

"This is without doubt going to be a very demanding tour. South African youth and age grade rugby is as good as any in the world and their school and academy structures are very strong."
