Heidi Klum has ridiculed Donald Trump after the US presidential candidate said she was "sadly no longer a 10" in a sexist remark about her looks. The billionaire Republican, who has made a string of offensive comments since declaring his bid for the White House in June, claimed the German-born supermodel was no longer as attractive as she once was."Sometimes I do go a little bit far," he said in an interview with The New York Times, in which he insisted he was not a misogynist. "Heidi Klum. Sadly, she's no longer a 10."In response, Klum, who is regularly voted one of the most attractive women in the world, posted a video on Twitter in which she poses for a photo shoot with a "10" on her T-shirt.She is then approached from behind by a man in a Trump mask, who rips off the "10" to reveal a "9.99" underneath.The 42-year-old shrugs and then smiles and carries on with the photoshoot.Trump is growing increasingly competitive in an election matchup against Hillary Clinton, trailing the Democratic frontrunner by six points in a poll yesterday.
