Monkey can reveal that BBC newsreader Kate Silverton is to present a special post-Olympics programme live from Heathrow on BBC1 on Monday afternoon. Called Olympic Heroes Return, she will exclusively interview the medal-winners as they land back on British soil in their gold-painted plane. Rumours that Silverton will change her name to Golderton for the occasion are wide of the mark.
