As the Minister of State Shashi Tharoor is still trying to make a way out of its controversy over the Kochi team with Lalit Modi, sources say that the spat between the two may cost Tharoor his Ministership.

In fact, as the Finance minister Pranab Mukherjee and defence minister AK Antony, who were appointed by Sonia Gandhi to investigate this matter have found Tharoor's explanation unsatisfactory, sources say that he may be asked to file his papers soon.

Moreover, it is believed that the Congress party now thinks that the minister's continuation in the government has become untenable after the latest controversy added fire to the sparks that were ignited over the rift on his two tweets he made on the micro blogging website Twitter.

It is most likely to be proved that Tharoor used his position to arrange sweat equity for his dear friend Sunanda Pushkar in IPL Team. However, according to the company law, a company can issue "sweat equity" only a year after commencing business, in section 79a.

But Rendezvous Sports was only registered in March 2010 making it a violation of the rule.
