In 1989 Westminster Council voted to expel homeless families from the borough's hostels. They were transferred to asbestos-ridden tower blocks in a safe Labour ward, often without heating or sanitation systems.
This was part of Westminster's "building stable communities" plan, which pumped investment into marginal wards in order to secure Tory votes while removing groups traditionally thought to vote Labour (such as the homeless, nurses and students).
It became known as the "homes for votes" scandal, described by a previous council leader as "simply criminal".
One pioneer of all this was council leader Sir Simon Milton. With such experience, his newly appointed position seems obvious: Boris Johnson's lead adviser for planning and housing.
