Reliance Industries Chairman Mukesh Ambani met Prime Minister Manmohan Singh today, seeking a windfall profit tax on the Reliance group's oil business.


Ambani started a series of meetings with ministers and top bureaucrats, presumably to explain that the WPT lacks economic logic.


There are reports that Ambani also met UPA Chairperson Sonia Gandhi, but no confirmation could be obtained.


Officials of RIL declined to comment on Ambani's movements in Delhi.


The Ambani visit to Delhi assumes importance in the wake of Amar Singh, perceived to be a close friend of Anil Ambani, opening a front against RIL.

In a recent interview, Amar Singh had said RIL's opposition to Anil Ambani Group's negotiation with MTN for a deal was "disgusting."


He had even suggested that the Prime Minister should intervene and bring about a rapprochement among warning Ambani brothers.
