Update 10.25am: Justice Minister Charlie Flanagan has launched a new media campaign questioning people's attitudes to sexual harassment.
The campaign, entitled 'No Excuses', will run for three years to 2021.
The campaign will operate across TV, radio, outdoor, social and digital advertising.
The Minister said research has shown that Ireland has "disturbingly high levels" of sexual harassment and sexual violence.
Update 7.40am: The number of sex crimes reported to the gardaí increased by 26% last year.
This morning the government will launch a new national awareness campaign aimed at tackling sexual violence and harassment.
"No Excuses" will feature ads on TV, radio, cinema and social media, showing different scenarios in a bid to get people to think about their behaviour.
CEO of the Dublin Rape Crisis Centre, Noeline Blackwell, says the campaign is much needed.
"The State, while they might put laws in place, has trouble highlighting how our society needs to change," she said.
