MP for Richmond Park Zac Goldsmith wants to tweak Government plans to give council tenants the right to buy.

The Conservative party's mayoral candidate proposed to make the Housing and Planning Bill more London specific, was backed by the other London Tory MPs.

The bill has just passed its second reading in the House of Commons on November 2.

David Cameron's bill, first read in October, would give housing association tenants the right to buy their rented homes with discount.

If this were passed, housing associations would then have to be compensation for the loss of housing stock.

The Government plans to raise this cash through councils selling 'high value' homes as they become vacant.

London Ministers fear housing stock could easily be lost through this method.

To safeguard against this Mr Goldsmith tabled an amendment to the policy, which would mean each sold council home with have to be replaced with two more.

James Berry, MP for Kingston and Richmond, said it is the first amendment he has signed so far as a minister.

He added: "I'm a supporter of the right to buy council houses. I've spoken to a lot of people wholes lives have been changed by the right to buy and what we've done is extended that to people in housing associations.

"I think the principle is a good one which people don't oppose. The problem is whether the replacement housing will be built, we don't want out social housing stock to go down, that's why Zac proposed that amendment."

Figures presented to the disbanded Community Housing Trust shadow board last month by Kingston Council head of housing Darren Welsh, showed the worst case scenario for Kingston could see the sale of four out of 10 homes which become vacant.

In addition to extending the right to buy to council tenants the bill would give authorities powers to tackle rogue landlords in the private rented sector.

It would also make provisions for 'high income' social tenants to pay a market rent as opposed to a social rent and would reform the planning system.

The bill has been sent to the Public Bill Committee and the committee is expected to report by December 10.
