The announcement followed a period of ill health for the duke, who was admitted to King Edward VII’s hospital in February.
He was then transferred to St Bartholomew’s hospital weeks later for heart surgery, and left on March 16 following a successful procedure.
While Philip had “no desire” to reach his 100th birthday, doing so could have seen him receive a special birthday card from his own wife.
The monarch is known to send letters to British citizens when they reach the big three figures, but it’s unknown if this would have been extended to her long-serving consort.
While those receiving a state pension don’t need to apply to receive a letter, as their details are taken from private records, everyone else has to request that the Queen gets in touch - five weeks or fewer before the special day.
We’re pretty sure she would have got him his own card anyway.
