The Wikipedia article on Marcia Falkender/Marcia Williams (private secretary to PM Harold Wilson) makes a rather explosive claim:
When Wilson lost office in 1970, Falkender seized his papers, and her brother, Tony Field, helped Wilson break into her garage to recover them.
(it states this smack dab in the middle of a paragraph in the 'Persona Life' section, with zero additional context offered)
The source given is an Independent article from 2006. The article does support the claim on Wikipedia:
When Harold Wilson lost office in 1970 and Marcia seized his papers her brother, Tony Field, obligingly teamed up with the ex-PM to break into her garage to recover them.
However, it does not refer to any further sources itself, or go into any more detail. These two places - the Wikipedia page, and the Independent article it cites as a source, are the only references I can find to the incident, anywhere (Wilson's own Wikipedia page does not contain the word 'garage', and googling 'harold wilson break into garage' does not turn up anything relevant).
Frankly, I find the whole thing rather odd. Surely, if a former Prime Minister of the United Kingdom had burgled a garage, that would be more widely known? I'd expect it to come up in TV quizzes, Youtube trivia videos...
Do any other sources support the story? Do any describe it in more detail?
