Viewers saw double during a BBC weather bulletin when two moving images of presenter Helen Willetts appeared on screen at once. A technical gaffe meant the forecast on Thursday became a two-cast as the BBC News channel presenter and her twin guided viewers through the outlook for the next few hours. News presenter Huw Edwards also appeared bemused when she handed back to him during the broadcast. He told viewers: “Not just one Helen, but two Helens, and, frankly, I’m happy with two, three, four, five Helens.” A BBC spokeswoman said: “We experienced a technical problem with our weather graphics which led to two Helens appearing instead of one.”
