Insurance liability requirements

[CKnopfell]

Hi,

I am looking to insure my C172. Is there a list of what the
insurance liability requirements are for different airports in
the UK? Ireland? France? Germany? Netherlands?

I am trying to choose between UKP 1M liability and UKP 3M
liability. I know some airports (eg Leeds/Bradford) require
more than 1M.

If you even have any general info on what the liability
requirements are that would help, esp. info on what they
are in the rest of Europe.

Thanks for your help,
Carl.
