The man who gave Ireland its most infamous TV blooper is to leave RTE, the national broadcasting company after 30 years.

A few years back, poor news presenter Aengus Mac Grianna was giving his face a bit of a touch-up, completely unaware that the previous news item had already finished and he was supposed to be fixing his eyes back on the teleprompter.
