Thanks SPB, I do have an IGS account but am at home this week.
I'm sure that someone at my place of work would be quite well genned up on these regulations but the Intraweb reference would be much appreciated.
JG: Just got off the 'phone to the WOMAA at DNSy regarding your enquiry and he informed me that Cuba has now been taken off the list of restricted countries. Therefore my reference to BR 8587 above is no longer appropriate. You can now travel to Cuba without permission from your CO.
However he did advise that there does remain a possible threat to British/Western nationals in Cuba, and that you should take the usual necessary personal security measures that you and your family would normally do when travelling in any foreign country (don't draw attention to yourself, overtly advertise that you are Forces, Sharkwatch, etc.)
Jimmy - Green, does it have to be Cuba you visit or is it that part off the world and Cuba has some good deals? I only ask because I'm recently back from Jamaica (90 miles from Cuba) and could recommend somewhere we got as a better deal to Cuba.
