This is particularly tough on young people and families but it affects people of all ages.
Purist ideological solutions are not the answer because both the market and the state have failed - the market has not delivered enough housing where it is needed but this has a great deal to do with state regulation. Britain's housing market is tightly regulated (as I should know having spent years on planning committees.)
The main reason young people and others on low incomes are being priced out of good options on the housing market is that Britain simply does not have enough homes in the right places. So a majority Conservative government will take the following action:
We are setting out a package of measures to build more homes, get people onto the housing ladder and make the renting market fairer.
