On 14 September 2010, he shared a debate with the NF publicity officer, Tom Linden, on BBC Radio Foyle about the support for the NF in Coleraine. Dallat expressed his disgust and was then criticised by Linden for being a member of a sectarian party, which allowed Dallat to air his views, which resulted in the NF Coleraine organiser, Mark Brown, "thanking" Dallat for helping the NF double its support in Coleraine through enquiries and membership.[8]
A member of the Society of Saint Vincent de Paul, Dallat commented that Conor Murphy had scheduled the 2016 opening of the Dungiven by-pass to coincide with the centenary of the Easter Rising, to which Sinn Féin councillor Paddy Butcher said: "Attacking Sinn Féin minister Conor Murphy, Mr. Dallat cautioned the residents of Dungiven to 'hope the Dungiven bypass is less of an aspiration and more something they (Sinn Féin) are actually capable of delivering'".[9]
After a short retirement, Dallat retained the SDLP seat in East Londonderry in the 2017 Assembly elections.
