Ryan Tubridy has revealed how a chance caller to his radio show led him to lend his support for a campaign against domestic violence.
He plans to follow in the footsteps of veteran broadcaster Gay Byrne by using his profile to discuss the problem across the airwaves.
Speaking at the launch of Safe Ireland's 'Man Up' campaign, the RTE star described how a caller to his 2fm radio show four weeks ago had recounted on air how she had been assaulted by her husband.
"She couldn't understand how the man she loved could do this to her with their kids upstairs. For us it opened the floodgates to hundreds of other calls from women in the same awful position."
Praising Byrne for first highlighting the problem on his daily radio show, the 39-year-old said he felt the "the baton" had now been passed to him.
"I'm not a natural born advocate but I give a damn, and I have a radio show with an audience. I want to try and stop this happening," Tubridy said.
"If a man hits a woman, it's no longer a domestic. It's intervention time. Be nosey. Get involved. The silence has to stop."
New figures show that nearly 8,000 women and 3,000 children received support from domestic violence services in 2011, up 15pc since 2010.
