have the right to sit in the House of Lords. The title exists only for the duration of their own lifetime and is not passed to their heirs (although the children even of life peers enjoy the same courtesy titles as hereditary peers). Some life peerages are created as an honour for achievement, some for the specific purpose of introducing legislators from the various political parties (known as working peers) and some under the Appellate Jurisdiction Act 1876, with a view to judicial work. There is a discrete number appointed as "People's Peers", on recommendation of the general public. Twenty-six Church of England bishops have a seat in the House of Lords. As a life peerage is not technically an "honour under the Crown", it cannot normally be withdrawn once granted. Thus, while knighthoods have been withdrawn as "honours under the Crown", convicted criminals who have served their sentences have returned to the House of Lords. In the case of Lord Archer of Weston-super-Mare, he has chosen only to exercise dining rights and has yet to speak following his release from his conviction for perjury. Baronetcy A baronetcy is the lowest hereditary title in the United Kingdom. It carries the title sir. A Baronetcy is, in the order of precedence, below a Barony but above most knighthoods. Baronetcies are not peerages. When a baronetcy becomes vacant on the death of a holder, the heir, if he wishes to be addressed as "Sir", is required to register the proofs of succession. The Official Roll of Baronets is kept at the Ministry of Justice (transferred from the Home Office in 2001) by the Registrar of the Baronetage. Anyone who considers that he is entitled to be entered on the roll may petition the Crown through the Lord Chancellor. Anyone succeeding to a baronetcy therefore must exhibit proofs of succession to the Lord Chancellor. A person who is not entered on the roll will not be addressed or mentioned as a baronet or accorded precedence as a baronet, effectively declining the honour. The baronetcy can be revived at any time on provision of acceptable proofs of succession. As of 2017, 208 baronetcies are listed as presumedly not extinct, but awaiting proofs of succession. As with hereditary peerages, baronetcies generally ceased to be granted after the Labour Party came to power in 1964. The sole subsequent exception was a baronetcy created in 1990 for
