Voting in the house of lords until 1867 was allowed by proxy if a peer or bishop was absent. Proxy deeds which enabled the absent peers and bishops to nominate their proxies had to be registered in a proxy book in the care of the clerk assistant. Until recently there was no record of a proxy book for 1661–2, it having been wrongly bound with proceedings for 1625–6. This note looks at the layout of this newly-found proxy book, and compares it with earlier and later books. The note ends with an analysis of the proxies recorded in the book and their importance for the political history of the period.
