IT journalist Guy Kewney was amazed to see another man appear on a plasma screen with a banner showing his name as he waited in the BBC News 24 reception for an interview.
The mix-up happened when a cab driver, who it appears was booked to pick up Kewney at the end of the interview, responded to a call for his name in reception.
It appears that the taxi driver did not realise the mistake even when he was led into a studio and wired for sound.
The real Kewney said on his NewsWireless blog: "Watch his incredible recovery, and his determination to show that this may be a complete surprise to him but that he can out-Kewney any darned NewsWireless editor if he has to."
