My Lords, the noble Lord, Lord Lexden, has a strong point and he has long campaigned on it with great energy and skill. He highlights much unfairness to siblings and other blood relatives who share households. It is not only inheritance tax; there are fiscal disadvantages in a number of areas, and disadvantages in landlord and tenant intestacy. Do the Government agree that while there is not a case—and we agree with this—for equating siblings and other blood relatives with civil partners, there is nevertheless a strong case for a number of reforms? Will the Government agree to establish a cross-departmental working party to look at these issues and consider what specific measures are necessary to address these disadvantages?
