"It (AAP) is a single issue-based movement. AAP is going strong where traditionally the Left is not strong," CPI(M) Politburo member Sitaram Yechury told PTI here.
The Rajya Sabha member said AAP represents a force which wanted a clean government and this particular idea was an international phenomenon which had emerged from the Tahrir Square movement in Egypt.
"They (AAP) talk about an ideal state, which is not corrupt, secular and also follow some democratic traditions. But we cannot achieve that ideal state from the abstraction of the economic policies that are already followed. I am sure, with experience they will get mature," Yechury said.
"Corruption is an outcome of economic policies. It is a part of crony Capitalism. There is no clarity on the issues that they are raising," he added.
When asked whether the CPI(M) and the Left was willing to form a post-poll alliance with AAP, Yechury said, "Many of the issues that they are raising, we have been talking about for long. Forming an alliance with AAP depends on them whether they want to join us or not."
He said the party was open to an alliance with anyone who was non-Congress and non-BJP.
