The actor didn't hold back in a message to the former London mayor, who on Thursday ruled himself out of the race to become U.K. prime minister.

Ewan McGregor made his feelings clear in a tweet directed at Boris Johnson, the former London mayor who led the successful campaign for the U.K. to leave the European Union.

Johnson had been the favorite to replace David Cameron after the prime minister announced he would be stepping down following the June 23 referendum. But in a shock announcement Thursday after days of wrangling among Conservative MPs, he ruled himself out of the race — a race many had said he had only entered in order to topple Cameron and take the reins.

For McGregor, who had already revealed his disappointment at the Brexit result, the decision by Johnson was just too much to stay quiet. In a tweet sent moments after the announcement, he described Johnson as "spineless" in leaving someone else to "clear up" his mess.
