Prime Minister Manmohan Singh and his wife Gursharan Kaur were shown black flags on Sunday by supporters of anti-graft crusader Anna Hazare at the Golden Temple.
A handful Hazare's supporters, including women, raised slogans against corruption and in favour of Lokpal as soon as Singh and his wife came out after paying obeisance at the Golden Temple.
The supporters also raised slogans asking the PM to go back (PM wapas jao). They also showed small black flags to Prime Minister.
Government failed to get the Lokpal Bill passed in the Rajya Sabha on December 30 after opposition from parties, including ally Trinamool Congress.
