France's Armenian Genocide Bill

Although it has been passed by both the lower house of the French parliament, controlled by the UMP and its allies, and the Senate, recently won by the Socialists and their allies, the proposed law has divided both the major parties.
A Senate committee even tried to prevent it being debated, leading the leaders of both parties’ Senate groups to hack a deal to persuade dissidents in their own ranks to abstain.
When it came to the vote only 57 out 132 UMP senators and 56 out of 130 Socialists backed it. Nine Socialists and 19 UMP members went so far as to vote against.
The Communists and their allies and the centrists were also split, although they officially supported the bill.
A number of senators either abstained or refused to take part in the vote.
Only the Greens and a cross-party group called the Rassemblement démocratique et social européen managed to maintain unity. They all voted against. From here.
