Prince Albert also attended the memorial service for Prince Philip in London in March this year together with other heads of states and extended royal family of Prince Philip from Germany, Romania, and Yugoslavia, in addition to members of the British royal family.

The ex-king of Greece, Constantine II, in his letter of condolence, expressed his devastation upon hearing the British monarch has died.

"We have been through so much together and I will never forget the love, tenderness, and support she showed me and my family. She will be greatly missed".

The former Greek king, whose father was a first cousin of Prince Philip, shared how Queen Elizabeth II had been so generous and kind to his family during the trying times of their lives. 

He was referring to the period he was forced to flee Greece with his family during the military coup that ousted him from the throne. They settled in Italy and later moved to the United Kingdom where they lived for the most part of their lives.
