His rivals have always charged Amar Singh with being a loose cannon,who doesnt give much thought before he speaks out,often to the embarrassment of others. However,last week the Samajwadi Party leader was at the receiving end of his own habitual indiscretion when he threatened to withdraw support to the UPA Government over lack of action against Pakistan,soon after a meeting with External Affairs Minister Pranab Mukherjee. Realising that he may have crossed the line,Singh called up party ideologue and chairman of SPs parliamentary board,Janeshwar Mishra,to clarify the stand. Amused by the situation,the veteran politician reminded Singh that while the party had braved poaching of MPs during the vote of confidence,it may not be wise to assume the support of more than 20 MPs this time. Moreover,with all the disqualifications from the Lok Sabha on grounds of defying party whips,the Congress may not be all that dependent on the SP. An embarrassed Singh had to do a turnaround.
