Mr Johnson is “painted into a corner” according to the Daily Mail’s headline which continues the papers’ home decorating wordplay. The paper says he and fiancee Carrie Symonds “may have to hand over personal emails and phone messages” to an official inquiry into how the flat renovations were funded. The Electoral Commission, leading the probe, “has sweeping powers to demand documents and interview witnesses”, the Mail notes. It even suggests Mr Johnson “could be first PM interviewed under caution”. Elsewhere, the paper pictures the Duke and Duchess of Cambridge on their 10th wedding anniversary.
