It's That Man Again (or, commonly, ITMA) was a BBC radio comedy programme which ran from 1939 to 1949.
 The title refers to a contemporary phrase concerning the ever more frequent news-stories about Hitler in the lead-up to the Second World War, and specifically a headline in the "Daily Express" written by Bert Gunn.
 This was humorously transferred to Tommy Handley, the popular comedian around whom the programme was developed.
 The scripts were written by the prolific Ted Kavanagh.
 "ITMA" is believed to have played a major role in sustaining morale on the UK's "home front" during the Second World War.

 George VI ascended the throne upon the abdication of his brother, Edward VIII, on 11 December 1936, three days before his 41st birthday.

The London Declaration was a declaration issued by the 1949 Commonwealth Prime Ministers' Conference on the issue of India's continued membership in the Commonwealth of Nations after its transition to a republican constitution.
 It was made in London on 28 April 1949 and marked the birth of the modern Commonwealth.
 The declaration had two main provisions: It allowed the Commonwealth to admit and retain members that were not Dominions, so including both republics and indigenous monarchies, and it changed the name of the organisation from the British Commonwealth to the "Commonwealth of Nations", reflecting the first change.
 The Declaration recognised King George VI as Head of the Commonwealth.
 Following his death, the Commonwealth leaders recognised Queen Elizabeth II in that capacity.
King George VI was the monarch of the United Kingdom, the British Commonwealth and the British Empire from 11 December 1936 until his death on 6 February 1952.
