Why do the Government refuse to accept that those who live together permanently in platonic relationships, such as sibling couples, are no less deserving and in need of fiscal and legal safeguards than those who marry or become civil partners? Is it just or right that, among other hardships, many platonic family couples should have to endure the terrible anxiety created by the potential loss of the much loved and jointly owned family home because inheritance tax has to be paid when the first member of the couple dies and cannot be deferred until the death of the second? Did the Conservative manifesto not promise to take the family home out of tax?
