Allegedly said in the 1930s while Leader of the London County Council, outlining a supposed Morrison policy of building LCC estates in Conservative-voting areas in order to shift elections towards the Labour Party. No source has been found and quote has not been traced earlier than the early 1960s. The Local Government Chronicle once offered a prize to anyone who could find proof that Morrison had said it; the prize remains unclaimed. Morrison's LCC built substantial numbers of homes but a large number of them were outside the County of London entirely.
