LONDON: Britain’s Prime Minister Gordon Brown forgot to turn off his microphone before he described a loyal Labour voter, Gillian Duffy, as a bigot for asking about immigration.

Brown, who is on campaign trail for UK elections on May 6, blamed advisers, particularly, Sue, for putting him up against Duffy, 66, and said it was a “disaster” ahead of next week’s election.

“That was a disaster, they should never have put me with that woman. Whose idea was that? It’s just ridiculous,” Brown was heard saying with the microphone still on in his ears.

Asked what Duffy had said to upset him, Brown told the aide: “Everything. She’s just a sort of bigoted woman.”

Duffy, who is a grandmother, met with Brown at a campaign stop and questioned him about the influx of immigrants, specially eastern Europeans, who have come to Britain. Brown satisfied her query but ended up with a gaffe that has made him lose the point he had tried to score on the campaign trail.
