German Chancellor Angela Merkel arrives for the resumption of talks on Friday morning.

It was a long night for everybody at the European Union summit in Brussels. As we report today, the 27 EU presidents and prime ministers began their talks at 7:30 Thursday evening and continued past 4:30 a.m.

The leaders then emerged to face the cameras, each aiming to spin the outcome in a way that would best please his or her domestic audience. After that, perhaps, a chance to sleep. But not for long -- the talks were due to resume at 9.30 a.m on Friday.

The politicians were not the only ones to pull an all-nighter. As The Economist's Charlemagne columnist writes, "We journalists are probably too bleary-eyed after a sleepless night to understand the full significance of what has just happened." 

The writer is too modest: the Charlemagne article is a good place to start if you would like to know more about the long-term implications of the summit.
