Fraud fears over London housing right-to-buy sales
It is over 30 years since Mrs Thatcher handed over the keys to Britain's first right-to-buy council home.
Since then, the policy has helped over 250,000 Londoners get onto the property ladder.
The government is currently offering discounts of £100,000 to attract even more buyers in London.
But with London's soaring property prices, there are large profits to be made from former council houses, with some owners re-selling properties for over £1m.
Critics believe the high prices to be made are making the right-to-buy scheme increasingly vulnerable to exploitation.
The Audit Commission annual report (October 2014) reported a 400% increase in right-to-buy fraud in London.
BBC Inside Out's reporter Mark Jordan investigates how the scheme designed to help ordinary home owners is open to exploitation.
