The WASG - the mostly West-German and largely trade union-based leftist split-off from the Socialdemocratic SPD - and the Linkspartei (formerly PDS) - the reformist successor party to East-Germany's communists - have formally decided on a proper merger of the two parties.
At parallel party congresses in neighbouring halls, delegates from the two parties voted for the merger with 97% (Linkspartei) and 88% (WASG).
The two parties already ran a joint campaign in the 2005 parliamentary elections, under the double leadership of former SPD leader Oskar Lafontaine and former PDS leader Georg Gysi, and got 8,7% of the vote. The PDS had actually changed its name into Linkspartei in expectation of the merger. The actual formalities have just all taken some more time.
In current polls the group hovers at about 10%.
The merger decision does still need to be approved in a countrywide vote of all the members of the two parties.
There is an amusing enough moment-by-moment report of the proceedings here, in German:

Wie PE 113-018 fast zum Stolperstein wurde
Interesting to see again that the former Socialdemocratic dissidents of the WASG are in fact, by any political standard, to the left of the ever-pragmatic former communists. The merger only took place after the WASG swallowed the fact that the Linkspartei had rejected one or two of its proposed changes to the party's founding text as too radical.
The WASG had wanted to include a sentence that "the personnel reductions in public service have to be stopped". But the former communists, more ready to envisage the compromises that would have to be made in possible government coalitions, weren't having it.
Last year, the merger had come into some trouble when the Linkspartei of the city state of Berlin clashed with the local WASG during state elections, with the oppositional WASG campaigning from the left against the local government coalition of Socialdemocrats and Linkspartei. Partly as a result, the former communists lost about half of their support, but thanks to a good SPD result the two parties continued their government coalition anyway.
