Soren gets invitation for UPA dinner

Meanwhile, reaching out to the Jharkhand Mukti Morcha whose five MPs will be crucial during the confidence motion on July 22, Prime Minister Manmohan Singh [Images] invited its chief Shibu Soren and other Lok Sabha members of the party to his dinner for UPA constituents on Sunday.

Invitations have been sent to all five JMM MPs, including Suman Mahto, Sudam Marandi, Hemalal Murmu and Teklal Mahto.

The invitation assumes significance as the JMM is said to be divided on whether or not to support the government.

Though its Chief Whip Teklal Mahto insists that all five JMM MPs will vote in favour of the confidence motion, Soren has not commented on the issue amid reports that he is in touch with the National Democratic Alliance as well following its offer to help make him the chief minister of Jharkhand.

It is also learnt that a group of party MPs will meet Congress President Sonia Gandhi [Images]. Meanwhile, the JMM postponed till Sunday the crucial meeting of its parliamentary Board which was scheduled for Saturday evening.
