What's behind London's housing shortage?

London's ever-changing skyline spells out the message that the city is expanding.

But are new properties being created to help people find affordable housing, or provide bankable investments for those with money to spend?

On Monday - we spoke to a family who live in a one bedroom flat but even with a £400,000 budget their dream of a three bedroom home seems as far away as ever.

Our desire to own our own homes has led to a huge decline in the number of council houses, as they have been purchased through Right to Buy. And that shortage has pushed people away from the centre of London.

Those rising rents have had a knock-on effect on the Government's cash too, forcing up the housing benefit bill - that means cuts to the service.

Help to Buy - intended to help people get onto property ladder - only really works in areas where property is cheap, and it simply isn't in London. The increasing trend is likely to continue - leave london, or pay the price.
