"Right to buy"?

"Boris Johnson wants to give millions of people the right to buy the homes they rent from housing associations in a major shake-up inspired by Margaret Thatcher."

"The Prime Minister ordered officials to develop the plans in the last fortnight after becoming convinced the idea would help “generation rent”, The Telegraph can reveal."

"The proposal is intended to give the 2.5 million households in England who rent properties from housing associations the power to purchase their homes at a discounted price."

-- Thus reducing the number of homes available to rent and pushing up rents for those who continue to rent (because inadequate supply means extra demand).
