Names of publications giving contact details of senior ministers,
civil servants and members of parliament in the following countries:

Belgium; France; Germany; Italy; Luxembourg; Netherlands; Denmark;
Ireland; Greece; Portugal; Spain; Austria; Finland; Sweden; Cyprus;
Czech Republic; Estonia; Hungary; Latvia; Lithuania; Malta; Poland;
Slovakia; and Slovenia

In the UK the equivalent publications would be the Civil Service
Yearbook (www.civil-service.co.uk) or Dod?s Parliamentary Companion
(www.dods.co.uk/publications/dods-parliamentary-companion/default.htm)

I am only interested in national government and legislatures, not the
European Commission or European Parliament.

I believe you will do better if you post each of these items as a
separate question (one for each nation).
