London - British Prime Minister Gordon Brown said in an interview Sunday that he has made mistakes in office but will do better in future.

Speaking to the BBC on the second day of the Labour Party's annual conference in Manchester, Brown said "you asked me had we made mistakes and I said yes ... Of course I always want to do better and I will do better."

Brown described his cabinet as "pretty united." He has been under pressure from poor poll ratings and an attempt by a handful of junior government ministers last week to seek a leadership contest.

An opinion poll published Saturday in the Daily Telegraph showed Labour trailing behind the Conservatives by 20 points.

Brown also received poor personal ratings, with just 16 per cent of those asked saying they believed he was providing strong leadership.

During a keynote speech to delegates on Tuesday, Brown is expected to say that he is the right man to guide Britain through difficult economic times, and that Labour should put aside its squabbles to tackle the challenge together. (dpa)
