And it's a goodbye from Mrs Peston …

Robert Peston 's appearance on the BBC Radio 5 Live breakfast show on Thursday morning was interrupted by an unscheduled intervention by his wife Sian . As the BBC's business editor was discussing the finer points of the credit crunch a muffled "Bye!" could be heard in the background. Peston didn't respond so she naturally tried again. "Byeeee!" This time he did respond, as did presenters Nicky Campbell and Rachel Burden. "If everybody listened to her, certainly if I listened to her, I would be in a lot less of a pickle than I am at this particular moment," said Pesto. Byeeee!
