it now gives me great pleasure in declaring bampton towers open. when you look back, you see photographs of the tenants moving in, often there were grand opening ceremonies, local dignitaries were there. people were moving from slums and they came to buckingham palace. by 1980, about a third of the population are living. in council homes. so it s a massive part of a history that affects nearly every family in one way or another. we are going to take you through the policies that have changed our housing estates. all the homes here were originally owned by the local council, lewisham. the first big change was in 1980. margaret thatcher introduced the right to buy. this is a very special day/ it is my great pleasure
