London-style rental price hikes will spread across the country unless the Government introduces strict regulation to deal with private sector rents, a Labour MP has warned.
Jeremy Corbyn also said that he was "increasingly concerned" about the role of housing associations, which are behaving less and less like the social housing providers they are meant to be.
He said the sector was completely unregulated and urged the Government to follow the example of Germany and others in bringing in protections, including l onger tenancies.
Moving a Bill under the 10 minute rule, Mr Corbyn said: "If we don't pass some strict regulation of the private rented sector now, particularly starting in London and the south east, the issue will spread all across the country as the private rented sector gets bigger and bigger.
"And when the Government tells me the cost of private rented accommodation is one of the main drivers on the very large housing benefit bill/housing allowance bill that we have in this country - I agree with them."
He added: "The way to deal with it is not to restrict the level of housing benefits that's paid to tenants. The way, instead, is to deal with it by controlling the rent level and the rent that is paid.
"Other countries seem to manage this very well and I just feel deeply angry when I meet people in my advice bureau every week who tell me they have been effectively socially cleansed out of an area they have lived in for a very long time, because their housing benefit is inadequate compared to the rent level that is being charged."
Mr Corbyn suggested that in some cases, housing associations were the problem rather than the answer.
"I remain and become increasingly concerned about the behaviour and conduct of housing associations; the way in which they increasingly outflank housing companies - not like social landlords - and increasingly seem to see themselves as in the property market rather than the provision of housing for people of desperate need, and I think that's an area that needs very tight regulation."
Mr Corbyn told the Commons that the private rented sector, currently 17% of housing stock nationally, was projected to rise to 22% by 2025. However, in some parts of the country - including in parts of his Islington North constituency - it is already "well over 30%".
He said: "My Bill would bring about better security - in the way they do in Germany where the tenancies are almost of a lifetime; will bring about better conditions for tenants living in those places, will also bring about much more stable communities."
As well as ensuring five year tenancy agreements, Mr Corbyn's Regulation of the Private Rented Sector Bill would enforce environmental and energy efficiency standards, and rent regulation.
A Second Reading has been scheduled for February 28, 2014, although it is unlikely to become law.
A similar Bill was introduced by Mr Corbyn in February, but it failed to complete its passage through Parliament before the end of the session.
