Chris Mason: Parties battle to be seen as the UK's housebuilders

The government lost votes in the House of Lords over a plan to help make it easier to build more homes.

It involved getting rid of a law which blocked development when there was a risk of water pollution.

The government claimed these requirements would stop 100,000 new homes being built before 2030 .

But green groups reckoned the plans were terrible and opposition parties opposed them.
