The largest resistance group, the National Liberation Front (EAM), was controlled by the Communist Party of Greece, as was the Greek People's Liberation Army (ELAS), led by Aris Velouchiotis, and a civil war soon broke out between it and non-Communist groups such as the National Republican Greek League (EDES) in those areas liberated from the Germans. The exiled government in Cairo was only intermittently in touch with the resistance movement and exercised virtually no influence in the occupied country. Part of this was due to the unpopularity of King George II in Greece itself, but despite efforts by Greek politicians, British support ensured his retention at the head of the Cairo government.
