For info just in case:
Driving in the EU after Brexit
The Government has confirmed that if there is ‘no deal’ then mutual recognition of driving licences between the UK and EU may end.
This would mean that UK drivers wishing to drive in Europe after 29 March 2019 would need to get an International Driving Permit (IDP):
A 1949 Convention IDP (Republic of Ireland, Spain, Malta, Cyprus), or
A1968 Convention IDP (all other EU countries, Norway and Switzerland)
It's been estimated that up to 7 million IDPs may be required in the first year if there's 'no deal'.
Whether there's a deal or not, the Government has decided that, from 1 February 2019:
IDPs will be issued by around 2,500 Post Offices (they're currently issued by 89)
The AA (and RAC) will no longer be permitted to issue IDPs
Mail order facilities for applying for an IDP will cease to exist
Hopefully an agreement can be reached to prevent further red tape and expense for drivers.

I'm going to wait and see what happens on the 29th March but we may need to pop along to the Post office between then and the beginning of May.
