The Commission completed an initial exercise in June, which revealed significant human rights concerns on a potentially systemic level.

Chief Commissioner Les Allamby, (pictured) said that the investigation will publish its findings in autumn of next year.

He added: “We know that research has shown that a quarter of Travellers residing in Northern Ireland have reported their place of residence to be unhealthy or very unhealthy, and many have also concerns about safety. A lack of footpaths, public lighting, fire hydrants, play areas, plumbing, washing facilities, electricity and refuse management are just some of the issues described.”

Mr Allamby continued: “A Housing Executive needs assessment has also outlined the need for appropriate accommodation for Travellers. TheNorthern Ireland Executive and other public authorities are required by human rights law to fulfill the right to adequate housing and must ensure non-discrimination.

“Examining these aspects in relation to Travellers accommodation will be the principal focus of the Commission’s investigation.”
