When populists take governmental power, they are faced with a challenge in that they now represent a new elite. In such cases—like Chávez in Venezuela and Vladimír Mečiar in Slovakia—populists retain their anti-establishment rhetoric by making changes to their concept of "the elite" to suit their new circumstances, alleging that real power is not held by the government but other powerful forces who continue to undermine the populist government and the will of "the people" itself. In these instances, populist governments often conceptualise "the elite" as those holding economic power. In Venezuela, for example, Chávez blamed the economic elite for frustrating his reforms, while in Greece, the left-wing populist Prime Minister Alexis Tsipras accused "the lobbyists and oligarchs of Greece" of undermining his administration. In populist instances like these, the claims made have some basis in reality, as business interests seek to undermine leftist-oriented economic reform.
