Rating (Empty Properties) Bill

My hon. Friend reminds me of an occasion when a pig farmer constituent of mine came to see me. He wanted to use his pig sheds for other purposes because, unfortunately, the demand for pigs was not as great as he had hoped. He wanted to turn the sheds over to light office use, and he has been fighting the planning system for several years. The buildings are still lying empty; I drive past them regularly. How much more difficult will the situation be when he has to pay a tax on top?
