Tributes have been paid to the former prime minister Baroness Thatcher who has died at the age of 87.
Perhaps her most visible legacy in Wales was the virtual disappearance of the coal mines and the birth of a new economy of service industries and technology.
BBC Wales economics correspondent Sarah Dickins reports from Newbridge, while Jamie Owen discusses the industrial legacy of the Thatcher era with former Labour minister and mining union officer Kim Howells and economic advisor Prof Patrick Minford.
