Liberal Democrat MEP Graham Watson said "it is time the EU puts flesh on the bones of policy needs identified at the last summit" in mid-October.
"Progress needs to be made, for example, on a more institutionalised approach to regulation. However, the danger of too much summitry is that governments begin to disagree. The conclusions of this summit should be concise and businesslike," he said.
