# Greek political leadership and internal tensions > Live situation record from CLSTR: https://clstr.news/situations/greek-political-leadership-and-internal-tensions > Updated: 2026-09-06T07:30:00.000Z. Sources: 48. Developments: 2. The Greek administration has experienced internal political shifts involving high-level advisors and former leadership. In August 2026, Sotiris Serbos, an Associate Professor and ad hoc foreign policy advisor to Prime Minister Kyriakos Mitsotakis, resigned from his position following friction regarding controversial remarks about U.S. policy toward Iran. By September 2026, tensions between Prime Minister Mitsotakis and former Prime Minister Antonis Samaras escalated into a sharp public confrontation during the 90th International Thessaloniki Fair. Mitsotakis reiterated that there is ‘absolutely no room for cooperation’ with Samaras, describing the former leader’s views on defense and foreign policy as an ‘insurmountable obstacle.’ Mitsotakis further suggested that Samaras possesses the ‘expertise to do harm to the party’ and urged him to protect his political legacy. Samaras responded with a scathing critique, asserting that the identity of the New Democracy party is determined by its members rather than the Mitsotakis family. He claimed that Mitsotakis ‘despises’ the electorate and characterized the current administration as being defined by ‘inflation, corruption, arrogance, and the impoverishment of the provinces.’ Samaras also criticized the government’s handling of taxation, migration, and foreign policy, and specifically attacked the administration regarding the Tempi train crash and wiretapping scandals, concluding that the current leadership represents ‘the Mitsotakis party’ instead of the historical New Democracy movement. In a direct video statement, Samaras predicted that Mitsotakis will be remembered in history as the ‘prime minister of corruption and economic hardship.’ In response to discussions regarding future electoral coalitions, Mitsotakis dismissed the prospect of a ‘government of the losers,’ emphasizing that New Democracy aims for a parliamentary majority to ensure stability. ## Claims - Antonis Samaras claimed that the current New Democracy leadership represents the Mitsotakis family rather than the historical political movement.
