DUBLIN (Reuters) -Ireland spluttered but did enough to beat Scotland 17-13 at the Aviva Stadium on Saturday and clinch back-to-back Six Nations titles for the second time in 11 years to put last year's World Cup disappointment behind them.

After England denied them a bid for successive Grand Slams last week, a sluggish Ireland looked at risk of relinquishing their grip on the title and giving the English something to play for in Paris after eking out an unconvincing 7-6 halftime lead.
