Thank you Vasu and Dinyaar. This was quite a revelation, as I never even considered using anything other that Indian plugs and sockets before. Usually I use an adapter, or I just cut the cable and replace it with an Indian plug. I have wired the whole house with MK sockets, and I use only MK plugs. I used to make my own extension boards using MK sockets, but have recently switched to using extension boards with the legend 'Oxygen'. They take all kinds of plug and have a nice and tight fit.
I have seen a number of attractive distribution boards when I travel abroad, but never considered bringing them home and using them here.
Only goes to show you learn every day.
Cheers
