Carolyn Harris, MP for Swansea East, says she mistook a grey button for the doorbell
It was not quite the grand switching on ceremony that Downing Street had anticipated for its Christmas lights.
A Labour MP has admitted she unwittingly turned on the lights early after mistaking the switch for a doorbell. Carolyn Harris, MP for Swansea East, attended a meeting at No 10 last Wednesday but said that, when the door failed to open, she pressed a grey button nearby.
