Britain's former Prime Minister Gordon Brown says he's not angling to replace the International Monetary Fund head who has resigned amid sexual abuse charges.

Brown thanked Dominique Strauss-Kahn for the work he did, saying Strauss-Kahn played "a very singular, important part" in the IMF's response to the global financial crisis.

Brown, 60, was Britain's treasury chief for 10 years and has long experience in dealing with the IMF. However, Brown said Friday during a visit to Johannesburg that he's "not making a pitch for a job."

Strauss-Kahn is accused of attacking a 32-year-old housekeeper Saturday in his hotel suite. He resigned late Wednesday, saying he needed to focus on clearing his name.
