The Fianna Fáil party in Ireland (the senior party in the governing coalition) is going to join the Liberal group in the European Parliament, after delegates voted in the party's Ardfheis (party conference) to accept the move. Provided that the Liberals accept them of course. It is unlikely to be much of a boost to the Liberals in the coming election, though as support for the party has collapsed in Ireland recently. Though since the party did so badly at the last European elections, there may not be a massive drop in the size of its delegation to the EP.
There are also plans to tighten rules about campaign funding for groups engaged in referendum campaigns. The move is clearly targeted at Libertas, whose funding has been a source of controversy and speculation ever since Lisbon I.
