Argar gave his maiden speech on 4 June 2015. He praised his predecessor, Stephen Dorrell and described the constituency as a post 2010 success story but said he would be "continuing to campaign for fairer funding ..for its schools." On other issues, he said that although the Government had made significant progress in dementia care and mental health provision, more was needed and he promised to vocally support those committed to further improvement. However he was there to represent the whole community in Charnwood, including those on the fringes and he passionately believed in one-nationism. Argar was opposed to Brexit prior to the 2016 referendum.
