2015 general election, Hall was elected to Parliament as MP for Thornbury and Yate with 41% of the vote and a majority of 1,495. In May 2016, it emerged that Hall was one of a number of Conservative MPs being investigated by police in the
United Kingdom general election, 2015 party spending investigation, for allegedly spending more than the legal limit on constituency election campaign expenses. However, in May 2017, the Crown Prosecution Service said that while there was evidence of inaccurate spending returns, it did not "meet the test" for further action.

2016 referendum. Since the result was announced, Hall has continued to support the official position of his party and now advocates leaving the European Union. At the snap
