"Are these new 3 pin hook ups, 3 pins in line? will the 2 pins still fit in? ie no earth? And where can you get the 3 pins from?"
There's a popular misconception that European mains connectors are "two pin" and don't have an earth. They do have Earth connections, but the earth is just arranged differently to the UK household plug.
In France and Belgium their plug has three connectors arranged in a triangle, just like the UK - except it has two pins and an earth socket - the wall point has two sockets and an earth pin.
In Holland and Germany, the CEE 7/4 (Schuko) plug has the same pin spacing as the French design, but the earth connections are two side-grippers.
There is a CEE 7/7 plug that has both the earth socket and the side grippers - and it's this type of plug that is sold in UK shops as a "universal" connector.
This "universal" connector may work in Italy as they have at least two standards for plugs - a derivative of the CEE 7 family with the earth pin in-line - a plug they call an industrial model which looks like the German Schuko (I've used this when on business) but the pin spacing may not be standard.
Hopefully more and more sites will adopt the IP44 blue 16 amp sockets and plugs.
