Cameron: Government needs to 'unblock' housing market

People in England are being offered help to climb onto or up the housing ladder as the government's mortgage indemnity scheme launches.

Building firms and taxpayers will be co-guarantors on new homes bought by existing or first-time buyers.

Critics argue the scheme is just a ruse to help the construction industry.

Prime minister, David Cameron, denied these claims and said that government assistance was aimed at helping more people onto the housing ladder.
