[UPDATED] Biggest party per country (Europe)

Please type the name of the political party that has the largest number of deputies (Member of Parliament) in each country of Europe. This quiz concerns only the lower houses (the chamber with the most power) when the legislative body is bicameral. It is therefore about each NATIONAL parliament, NOT the EU parliament. While the biggest party is often the one ruling the country, it can happen that a coalition of several smaller parties make up the government and therefore that the biggest party finds itself in the opposition (examples outside of Europe: Brazil and Argentina).
