It's been another important, interesting, really quite exciting day of European debt crisis action.

Here's a closing summary:

• The German constitutional court has rejected an attempt to block the introduction of Europe's new bailout fund. In an eagerly awaited ruling, judges in Karlsruhe ruled that the European Stability Mechanism did not violate German law.

However, they also imposed some tough conditions that mean German MPs must vote before the country's total exposure through the ESM is extended. Live coverage from here, handy summary here; photos here, final story over here.

• In Greece, mass strikes have taken place. Even military officers took to the streets of Athens, following a march by municipal workers. The protests took place as it emerged that Greece might not get its next aid tranche until November.

• Voters in the Netherlands have been voting in its general election. Exit poll data will come tonight, but the likely scenario is a left-right pact between the two centrist parties. Here are some photos from the polling stations.

• EC president José Manuel Barroso has called for a European Federation. In his State of the Union address, Barroso argued for stronger political and economic union.

Such a move would require a new treaty, triggering referendums across the EU. Project Europe moves on.

We'll be back tomorrow to analyse the Dutch election results, and track the latest developments across the eurozone (including the results of another meeting taking place tonight in Greece between the coalition leaders).

Until then, thanks and goodnight!
