I enclose my letter to the Rt Hon James Arbuthnot, my MP, for reference...
Dear Mr Arbuthnot,
I am writing to you in your capacity as my Member of Parliament in order to draw your attention to the situation of Mr Tul Bahadur Pun, who on 23 June 1944 was awarded the Victoria Cross for his actions at Mogaung, Burma, whilst fighting against the Japanese. You may be aware that he has recently applied to emigrate to the UK because his failing health means that he is unable to receive the specialist health care that he requires in Nepal. This application was turned down due to his having "failed to demonstrate strong ties with the UK".
I am a serving Officer in the Royal Air Force, who has served in both Iraq and Afghanistan and who voted for you at the last election, and I am disgusted that my government has treated so shabbily someone who so obviously warrants our eternal gratitude and respect. If ever there was someone whose case history demanded and deserved a review, I suggest it is Mr Pun. This decision is a disgrace; I strongly and humbly beseech you to raise Mr Pun's situation as a Parliamentary Question at the earliest possible opportunity, and for you to use your political influence as the Chairman of the Defence Committee to help overturn this demonstrably unjust decision immediately.
Mr Pun is elderly and deserves our assistance now - please help us show him and the rest of the country that "loyalty, courage and good conduct" are not just idle words on my RAF Commissioning Scroll, but are traits that should be admired and rewarded, and that are manifestly embodied in Mr Pun's actions.
Yours sincerely,
etc etc
This decision can be rescinded, but only if we all get involved and take a stand. Spend 5 minutes now to write to your MP!
