I emailed The office of HM Queen Elizabeth II Here.
I have just sent the following:

Quote::

Ma’am,
may I bring to your attention the plight of Tul Bahadur Pun VC who has been refused entry into this country.
I respectfully beg that you use your good services to enable this brave man who has served this country so well to be allowed to enter the United Kingdom.
I remain,
your obedient servant,

Sgt.M.R.McGregor
