The Transport Minister Paschal Donohoe has denied reports that fewer than half of drink-drivers end up being prosecuted.

Mr Donohoe says the actual conviction rate is 86% - and not as low as 40%, as was claimed in one newspaper.

A report in the Irish Times last month said only 40% of summonses for drink-driving led to convictions.

The report also claimed the rate for the first five months of 2015 stood at just 28%.

It said that Kerry courts had the lowest conviction rate at 28%, while Offaly had the highest at 68%.

But in the Dáil, Minister Donohoe said the figures were seriously misleading.
