Gloucester 16 Leicester 44: Leicester landed their fifth Premiership title - and first since 2002 - as they moved to within one victory of an unprecedented trophy treble by blitzing Gloucester at Twickenham.
The Tigers ran in seven tries, including scores for new Leinster signing Shane Jennings and former Ireland U-21 international Frank Murphy, as they were crowned champions in emphatic fashion, completing a league and cup double after lifting the EDF Energy trophy last month.
Victory over Heineken Cup final opponents Wasps at Twickenham tomorrow week would see Leicester complete a remarkable hat-trick in head coach Pat Howard's final season before he returns home to Australia.
Gloucester, despite finishing top after the 22-game regular season, offered merely token resistance as Tigers ran in tries for wing Tuilagi (2), skipper Martin Corry, scrum-half Murphy, flankers Jennings and Lewis Moody, plus fly-half Andy Goode, who also slotted three conversions and a penalty.
The west country club proved a crushing disappointment, seemingly in awe of the occasion as they proved unable to unleash their exciting backs Ryan Lamb, Anthony Allen and James Simpson-Daniel.
But Leicester were in no mood to offer condolences, cruising home without seriously breaking sweat in front of a 59,000-strong crowd.
