"We have extended our moral support to Ramdev and about 5,000 dabbawalas feel that the cause for which he is undertaking the fast is just," said Raghunath Medge, president of Nutan Dabbawala Trust.

Volunteers of India Against Corruption (IAC), which was at the forefront during social activist Anna Hazare''s fast against corruption in April, joined other supporters of the yoga guru by undertaking a fast at the Azad Maidan.

The volunteers distributed stickers in offices and shops to make people aware of the menace of corruption.
