I too recently visited Palestine with Christian Aid and put it in the Register of Members' Interests. Does the hon. Gentleman agree that it is not just a case of illegality and taking land? The barrier separates farmers and families from the crops that they must grow, attend to and harvest. It separates school children from their schools. It separates sick people from the hospitals that they desperately need. That adds up to a real humanitarian crisis beyond notions of illegality.
