Hi All, just to confirm we pulled our UK edition out of Singapore completely in September due to local licence restrictions of our Asean edition, which has since ceased. Thanks to this thread I have spoken to our overseas distributor and can confirm that distribution of the UK edition has now been re-instated with our distributors in Singapore and Malaysia, effective April 2011 issue. They are also investigating supply/distribution to all territories that used to receive the Asean edition. I hope that helps.
And yes back issues can be purchased - as Andrew has highlighted already.
Best wishes
