One Defence Forces officer is going to get a serious talking to later on, we reckon.

RTÉ cameras have been following the progress of the Easter Sunday 1916 Parade, which is taking a 4km route through the streets of Dublin and past some of the key sites of the 1916 Rising.

But one lad stopped to take a phone call at just the wrong moment, with the cameras capturing him chatting away as President Michael D. Higgins walked past.

Look at this @defenceforces chap on the phone. His mam's going to box him, even though it was probs her. #rte1916 pic.twitter.com/nj1QP77LBi

That poor officer on the mobile phone behind the President is going to get his arse handed to him later #1916LIVE
