The holders registered an easy win at Stradbrook yesterday and victory over Ulster next Saturday will see them clinch the championship. There were two changes to the team that beat Connaught. Shane Moore partnered Simon Keogh in the half back division while Donovan Rossi filled in at centre.
On 20 minutes Leinster's Des Dillon struck from the back of the scrum, and this spurred Leinster with further scores coming from Fiachra Baynes and James Norton.
The Exiles held their opponents scoreless for awhile after the interval but Leinster scored again through Aidan Kearney and Keogh.
The Exiles registered two late tries from Kevin Burke and Gary Higgins.
