It is a second loss in the space of seven days against Irish sides for Glasgow, following last weekend's defeat at the hands of Munster.

Having twice gone in front, the visitors saw Ben Gissing, James Norton and replacement James Downey cross the whitewash - with six out of seven kicks from scrum-half Brian O'Meara completing Leinster's win.

In a low-key opening which saw Leinster outside-half Matt Leek off injured with an ankle injury, Gary Ella's charges took the lead four minutes later with a 15-metre penalty from O'Meara, just left of centre.

Glasgow however struck for a 14-6 lead after 25 minutes against the run of play, chalking up their first try in the 18th minute.

A fine Dan Parks touch saw the Scots claim line-out ball, and full-back Glenn Metcalfe chipped forward to glean a fortunate rebound off Felipe Contepomi to go under the posts.

Parks converted and following a second O'Meara penalty and flanker Donnie Macfadyen's third sin-binning of the competition in the 23rd minute, Glasgow hooker Gordon Bulloch managed to step inside Norton to bulldoze over.

Scottish international Parks again converted but Leinster ended the half in front - with nine minutes of the first period left lock Gissing crashed over in the left corner after a quick O'Meara tap.

The scrum half converted and Norton claimed his third try in two games in the 35th minute for an 18-14 lead.

Parks ran matters after the restart, chipping in with 10 quickfire points.

He started with a 43rd-minute penalty - with Leinster hooker Peter Coyle outpaced by Jon Petrie on the right flank, the Glasgow skipper's offload saw Parks touch down and convert for a six-point advantage.

Four minutes shy of the hour mark the Lions regained the lead through replacement Downey, touching down for his first provincial try off a Gary Brown inside flick.

O'Meara's kick clipped Leinster in front by a single point into the drizzle.

O'Meara and Parks, who finished with 20 points, exchanged penalties with the Scot twice closing the gap back to one point in the 74th and 79th minutes.

Parks had a chance four minutes into injury time to steal the win - but his kick went to the right of the posts.
