Southwark Council have seized back over 300 Council houses after discovering widespread abuse by tenants. Authorities found properties were being illegally occupied or sublet by fraudsters.
Councillor Richard Livingstone says it is important for the council to act as there are currently 20,000 families on the housing waiting list.
There have also been cases of tenants buying property under the right-to-buy act illegally.
Councillor Livingstone says some cases have been traced and prosecuted with the property returned to the council.
