The Spanish presidency unsuccessfully tried to challenge the European Council president's prominent post during the first rotating presidency of 2010, while the second half of the year saw a Belgian rotating presidency marked by a weakened caretaker government which did not challenge Herman van Rompuy, himself a Belgian politician.

Herman Van Rompuy and bilateral summits, such as the tense 5 October 2010 EU-China summit. He called a special European Council at short notice in early 2011 on the emerging Libya crisis, which, in agreeing conditions for military intervention, made it impossible for Germany to oppose such intervention once the conditions were fulfilled. On 1 March 2012 Herman Van Rompuy was re-elected unanimously as President of the European Council by the heads of state or government of the 27 EU member states. President Van Rompuy's second term has lasted for two and a half years, from 1 June 2012 to 30 November 2014.
