From the outset, prime ministers attempted to propose candidates or lobbied to influence the monarch's decision on appointments, but the Royal Household adamantly guarded information about potential names.[1] After 1931, when the Statute of Westminster came into being and the Dominions of the British Empire became independent countries, equal in status to the UK, the Order of Merit continued as an honour open to all these realms and, in many, became a part of their national honours systems.[12] The order's statutes were amended in 1935 to include members of the Royal Air Force and, in 1969, the definition of honorary recipients was expanded to include members of the Commonwealth of Nations that are not realms.
