Tennant admitted that he preferred to keep out of debates about the UK’s future because he feared celebrity status could sway some voters.
Despite this the actor, who grew-up in Bathgate, West Lothian, felt it was inevitable that his thoughts on major issues would come to the fore.
He said: “My personal views will come out in interviews because I end up talking about them.
“But I don’t expect other people to follow them just because they’re mine.”
Tennant stated that if he could go on ‘Question Time‘ he would but he felt that there were “cleverer people who could do it better” and had his own reservations.
He continued: “If I really believed I could make a difference, I would.
