Rattled by Baba Ramdev proposed indefinite fast over black money and corruption, the Government on Tuesday made an all-out effort to placate the yoga guru. While Baba Ramdev remained determined to proceed on the fast, Prime Minister Manmohan Singh himself urged him to give up his agitation while Finance Minister Pranab Mukherjee and Central Board of Direct Taxes (CBDT) officials were in direct touch with the Guru.
