PETER Capaldi and Alastair Campbell were left embarassed when their sponsored swear-off for charity was accidentally broadcast to a creche.
The Thick of It star and the former Downing Street press chief were appearing at a charity day at the headquarters of City trader BGC.
They were talked into the ‘swearathon’ in order to raise money for the Leukaemia and Lymphoma Research team, and their diatribes were broadcast across the entire building until organisers realised that they were audible in the children’s creche downstairs from the trading floor.
Mr Campbell apologised to “the kids and their mums and dads, and anyone else who took offence”.
“Our only defence is that the traders looked in need of a laugh after a day spent trying to humour celebs, and we were raising money for our respective charities,” he added.
Campbell won his swear-off against the Glaswegian actor by managing to cram eleven uses of the f-word into a one-minute speech.
