Research undertaken at the University of Manchester (UoM) highlights how limited resources and poor coordination at the heart of the Greek government (the core executive) have circumscribed Prime Ministerial authority and severely hampered the ability of successive governments to develop and implement policy. This issue is particularly pressing, as many of Greece’s recent economic woes can be attributed to this weak ‘reform capacity’. The research had a direct impact by changing party policy and informing the drafting of two new laws on restructuring the Greek core executive, in 2011 and 2013 respectively. These changes have survived the turnover of two different governments. Research findings have also been given extra impetus, with the strengthening of the Greek core executive identified in 2012 as a key priority by Greece’s international creditors – namely the International Monetary Fund (IMF), the European Commission (EC) and the European Central Bank (ECB).
