England Under-20s secured their first Six Nations Grand Slam since 2011 on Friday night after surviving a late scare to beat Ireland 14-10 at Donnybrook Stadium.
The visitors had a comfortable lead at the break thanks to tries from Jack Nay and Henry Walker and two conversions from Max Malins.
But Ireland fought back, with Bill Johnston kicking in a penalty before Gavin Coombes crossed just after the hour mark.
Johnston’s conversion handed hope to Ireland with the hosts reducing the deficit to just 14-10.
England, though, held on despite errors in their game in the latter stages of the match and further pressure from Ireland to secure a 14-10 win in Dublin, which seals their first Grand Slam for six years.
