The actor had left Mumbai in the morning today to meet the Gandhian Crusader and was to break his Ramzan fast at Ramlila Maidan.
According to reports the actor had written to the Prime Minister urging him to consider Anna's Lokpal.
The actor is a supporter of Anna's Jan Lokpal Bill. Aamir has been requested to keep a low profile during his meeting.
Sources reveal that the actor is in constant touch with Team Anna. He was the first Bollywood actor who extended his support to the septuagenarian.
Aamir is also of the opinion that the Prime Minister should come under the Lokpal ambit and the CBI's anti-corruption cell and Lokpal should come together and the lower bureaucracy also should be brought under the purview of the Lokpal.
Meanwhile, Anna's fast has entered its 12th day today and doctors expressed worry over the Gandhian's deteriorating health condition. Anna lost 7kgs and his blood pressure also dropped down.
