I apologise that looks exactly what I want, am I right in thinking that I can plug the lead into caravan and I could also plug another plug into the plug itself? Once I’ve clarified that I’ll order one, I won’t have a use for the other plug access and can’t really see what it would be used for.

Whilst it dangles on the powered van end of your EHU lead and is commonly called a "plug" in so far as it "plugs in", it is as stated actually like any other lead live end, a "socket".
As shown in my earlier link features a Euro socket for plugging in any device extension with a Euro plug [ a Schuko],
or you might simply use a travel adaptor like this

However, take on board that unless the bollard like most proper UK site bollards features an RCD, there will not be earth leakage protection.
We use it exactly as it appears you want, as a mains outlet in the awning, in our case for our hotplate/oven unit.
If you are going to use sites with rudimentary unprotected mains outlets, then use an in line RCD or don't use the Euro feature; any proper electricity inspected site is going to be protected.
Edit: you could buy a cheap inline RCD and wire it into the "fly-lead" featuring the right angled socket, or buy a made up expensive unit
As this
I have a portable RCD but these days never find I need it camping, only gardening.
