Hiya!
Can anyone suggest what the best way of searching for an MBA programme is?
Thanks
Kitty

I would suggest go through the information of mba sites providing worldwide information, look f.ex. here on this website, Find MBA, you will find detailed information. It's perfect to get a very good overview.
To evaluate the international standing of each program, you should consult the MBA rankings.

Hi Kitty,
did you find the information you needed? Depends what you want to do, I could maybe give you some more hints.

In any case, be careful, there are schools you should avoid because they are not serious and only after your money.
Besides the rankings, a sign of quality is accreditation of a school, but probabaley you know that?
