The Congress Party on Monday taunted anti-graft crusader Arvind Kejriwal by saying that their block level spokesperson would be too much to handle if both squared off in a debate.

The taunt came a day after Kejriwal challenged Prime Minister Manmohan Singh and party chief Sonia Gandhi to a public debate on corruption and  scams.

Using the medium of micro-blogging site Twitter to respond to Congress leader Digvijaya Singh's verbal and written vitriol against him, Kejriwal had mentioned that he would reply to all his questions in a public debate with Sonia Gandhi and Manmohan Singh, if the latter could convince them both to attend.
