EU summits are often more a barometer of mood than a venue for productive discussions. Some prime ministers use the Brussels stage to address their domestic audience.

Other heads of government, on the other hand, succumb to the temptation to push their own agenda in the slipstream, even if objectively they contribute little to solving the problem.
