In some cases the seal is replaced by a wafer version, a smaller representation of the obverse of the Great Seal embossed on coloured paper attached to the document being sealed. This simpler version is used for royal proclamations, letters-patent granting the royal assent, writs of summons to Parliament, licences for the election of bishops, and commissions of the peace. It formerly constituted treason to forge the Great Seal. The Great Seal of the Realm is in the custody of and is administered by the Lord Keeper of the Great Seal. This office has been held jointly with that of Lord Chancellor since 1761. The current Lord Chancellor is Robert Buckland. The Constitutional Reform Act 2005 reiterates that the Lord Chancellor continues to be the custodian of the Great Seal. The Clerk of the Crown in Chancery, who is also Permanent Secretary of the Ministry of Justice, heads Her Majesty's Crown Office, and is responsible for the affixing of the Great Seal. He is assisted by the Deputy Clerk of the Crown. Day-to-day custody is entrusted to the Clerk of the Chamber, and subordinate staff include a Sealer and two Scribes to Her Majesty's Crown Office. Section 2 of the Great Seal Act 1884 governs the use of the Great Seal of the Realm:  The Great Seal for each successive monarch is inscribed with the monarch's names and titles on both sides of the seal. Some of those used in the past are shown below. Where the inscriptions on both sides of the seal are identical, only one is given. Where they are the same except for the use of abbreviations, the one with the fuller forms is given. Where they are different, they are shown separated by a slash.
