The trust’s hospitals have a long association with the Royals dating back to 1970 when the Queen officially opened Northwick Park Hospital.
Thousands of well-wishers turned out to greet Her Majesty including (iron) lady in waiting Margaret Thatcher, the then Secretary of State for Education and Science.
There have been subsequent royal visits by Prince Charles, Princess Diana, Sophie of Wessex and the Duchess of Gloucester.
American ‘royalty’ in the shape of Senator Edward Kennedy also paid a visit to Northwick Park in 1971.
Kennedy, who was tipped to be the next President of the United States, made it his first port of call after touching down at London Airport.
It was part of a fact-finding tour for the Chair of the US Senate sub-committee which was drawing up plans for a revised health plan for the United States.
Senator Kennedy, the younger brother of the late President John F Kennedy, wanted to see the ‘front line of the National Health Service’ and spent talking to patients and staff during his tour.
The 39 year-old was particularly interested in admissions and length of stay before moving onto a health centre in Wembley where nine GPs worked under the same roof as council welfare and medical services.
