Morris was opposed to Brexit prior to the 2016 referendum. He stated his reason for supporting remaining in the European Union was because he was "standing at the side of the Prime Minister on this one, because the Prime Minister has always stood by me and my people in Morecambe". Morecambe and Lunesdale voted narrowly to leave the European Union. Following the referendum he supported the position of his party and became committed to the UK leaving the European Union.
