President Michael D Higgins has said this year's Olympic Games had exposed serious issues for Ireland on doping and sports administration.

At a reception for Team Ireland at Áras an Uachtaráin, the President said these issues had the potential to undermine public confidence and fairness if not adequately addressed.

"Issues of doping, alas never far from the Olympic story in recent years, questionable decision-making by referees and judges during the games, and the controversy around the administration of our sports all deserve serious analysis and fearless responses here at home and internationally.

"Each of these issues, if not adequately addressed, has the potential to undermine public confidence in our athletes, in our sporting administration and in the fairness of international sporting competition itself," he said.

The President congratulated the athletes for representing Ireland on the world stage.

He said their performances had been inspirational and the whole nation had relished the highs and suffered the lows.

Silver medal winner Annalise Murphy, along with Thomas Barr and Scott Evans, were among the 26 athletes at the reception.

Mr Higgins paid tribute to her and Ireland's other silver medallists, rowers Paul and Gary O'Donovan.

"By the evident passion shown by Irish sportsmen and sportswomen in the past three weeks, by your hard work and years of dedication to achieve excellence and by the pride you so clearly have in representing your country at an international level, simply by getting to Rio and competing as one of the world's best in your discipline, you have succeeded and accomplished great feats."

He also noted that Irish results from the 2016 Olympics surpassed the previous three Games, with 14 top-ten finishes compared to eight in London, and 14 top-20 finishes compared to four years ago.

Minister for Sport Shane Ross and Junior Minister Patrick O'Donovan as well as acting president of the Olympic Council of Ireland Willie O'Brien were also at the reception, hosted by President Higgins and his wife Sabina.

The O'Donovan brothers are due back in Ireland tonight following the World Championships in Rotterdam, where Paul won gold in the Men's Lighweight Single Sculls.

None of the Irish boxing team was at today's reception in Dublin.

IABA to investigate betting allegations

The President of the Irish Amateur Boxing Association (IABA) has said the association will be investigating allegations of inappropriate betting by two Irish boxers during the Rio Games.

Speaking on RTE's This Week, Pat Ryan said he was appalled by the allegations, but it was important to allow due process to take place.

He said the IABA would await a report by the International Olympic Committee into the matter and would follow its own disciplinary procedures.

Mr Ryan said he had not spoken to the boxers alleged to have been involved in the betting, but he intended to do so.

He said in light of the controversy, he was going to propose to the boxing council that the IABA implement the recently adopted regulations of the IOC regarding gambling at Olympic Games.
