The role of President-in-Office of the assembled European Council is performed by the head of government of state of the member state currently holding the Council Presidency. This presidency rotates every six months, with every three presidencies co-operating on a common programme in triplets, meaning there is also a new president of the European Council every six months. The agenda of the meetings are defined by the Presidency, hence it may be misused by the country holding the Presidency by pushing their national interests up the agenda. The presiding country may also have additional negotiators at the table.The role as President-in-Office is in no sense equivalent to an office of a head of state, merely a primus inter pares (first among equals) role with other European heads of government. The President-in-Office is primarily responsible for preparing and chairing Council meetings, and has no executive powers. It does however offer external representation of the council and the Union and reports to the European Parliament after Council meetings and at the beginning and end of the Presidency.
