Former British prime minister Margaret Thatcher is recuperating at an unnamed hospital in the UK after undergoing a bladder operation.
Friend Tim Bell said 87-year-old Mrs Thatcher went to see her doctor after experiencing some discomfort and had what he described as a "small growth" removed.
He added late yesterday that the operation was over and had been "completely satisfactory".
Mr Bell said he could not go into detail as to the nature of the growth and declined to name the hospital, saying he did not want it to be inundated with calls.
Mrs Thatcher, who was dubbed the Iron Lady, has been in uncertain health for several years, having suffered a series of small strokes more than a decade ago.
