Britain's Chancellor George Osborne this week made housing one of his biggest priorities in the Autumn Statement, a bi-annual budget review. Osborne pledged a raft of measures that, taken together, aim to deliver 400,000 new "affordable" homes in England over the next five years. But a host of big property companies have "serious concerns" about his plans, which many think will benefit the already well-off while hitting the country's poorest.
