The Congress appears to be turning on the heat on the Samajwadi Party in Uttar Pradesh. A day after the former UPCC chief, Salman Khursheed, lambasted Mulayam Singh Yadav, the party lodged a protest with the Election Commission against the film star Amitabh Bachhan inaugurating blood donation camps inorder to help the SP. The AICC general secretary, Ambika Soni, today wrote to the CEC alleging that Mr. Bachhan and the SP leaders were using the blood donation camps and the distribution of artificial limbs to gain political mileage. ``These camps are being synchronised with the election campaign and they amount to an offer of allurement to the voters'' she added.
