Some viewers iewers have complained that the Christmas Day show by comedy duo Matt Lucas and David Walliams on BBC1 was racist.
The spoof documentary set in an airport and called Come Fly With Me featured the pair as a range of minority characters.
Lucas darkens his face and wears a beard to play a Muslim worker called Taaj. He also adopts a strong West Indian accent to play a black woman called Precious who works in the coffee shop.
Walliams's roles include a Middle Eastern passenger liaison officer called Moses.
However, some viewers failed to see the funny side and took to internet forums to complain about the programme – the first of a six-part series – likening it to a minstrel show .
The show, broadcast at 10pm, was the second most-watched show on Christmas Day, attracting an audience of 10.3million.
BBC1 bosses said they had not yet established how many complained to the corporation. A BBC spokesman said: Come Fly With Me had a huge audience and many people loved it.
Comedy has a social function and part of that function is to ruffle feathers, said Lucas. On Twitter he added: Like in Little Britain we try to reflect, affectionately, the multicultural Britain we love. No offence is intended.
