NASSAU, Bahamas, CMC – The Bahamas Monday joined the international community in paying tribute to Margaret Thatcher, described as Britain’s most dominant prime minister since Winston Churchill. Thatcher, 87, had been in declining health for some years, suffering from dementia. She died peacefully following a stroke. Observers said the death of Sir Denis Thatcher, her husband of 50 years and closest confidante, intensified her isolation in what had proved a frustrating retirement, despite energetic worldwide activity in the early years.
