As an MP, Stewart expressed his support for fox hunting, and was marked as a "For" voter to upkeep the traditional sport if it were voted on. He has been seen at hunt meets in his local area. He said, "I'm in favour. It's an important cultural tradition in Cumbria going back many hundreds of years, and hunts like Blencathra and Ullswater are a very important part of rural tradition. It's not something I've ever done myself but it's something I think people should have the right to do."
