He was duly returned as an MEP for the North West England constituency in the election held on 23 May. Later, in August of that year, Bull was adopted as the Brexit Party's prospective parliamentary candidate (PPC) for Central Suffolk and North Ipswich then subsequently Sedgefield in the 2019 general election.

Following the UK's withdrawal from the European Union on 31 January 2020 Bull's term as member of the European Parliament came to an end.
