British Prime Minister Gordon Brown said on Wednesday that US Senator Ted Kennedy, following his death at the age of 77, would be mourned around the world for his work to champion equal rights.
"Senator Edward Kennedy will be mourned not just in America but in every continent," Brown said in a statement.
"He is admired around the world as the senator of senators. He led the world in championing children's education and health care, and believed that every single child should have the chance to realise their potential to the full. Even facing illness and death he never stopped fighting for the causes which were his life's work," Brown added.
The Prime Minister said he was proud to count Kennedy as a friend and he recalled that Britain had recognised his service this year with the award of an honorary knighthood.
Kennedy played a major role in establishing peace in Northern Ireland, helping to smooth the negotiations which led to the 1998 Good Friday Agreement ended decades of strife in the British province.
The brother of former President John F Kennedy died after a long battle with a brain tumour.
