In August 2018, UKIP leader Gerard Batten MEP announced that there would be a membership ballot for the leadership of UKIP in Wales. The eventual winner would become the UKIP Assembly Group Leader and ultimately the party's main spokesperson for Wales. Hamilton, Jones and another UKIP Assembly Member in Wales, Gareth Bennett, stood in the election, which was won by Bennett. Hamilton said he could "happily" work with Mr Bennett, but Jones said she had "a lot of thinking to do". Batten said he expected his Welsh Assembly members to now "work together for UKIP's cause and get on with the job."
