Starting his two-day Uttar Pradesh visit with a scathing attack on the opposition, Prime Minister Narendra Modi today raked up the claim that Rahul Gandhi had recently called the Congress 'a party of Muslims'. He also questioned the motive for arch rivals, Mayawati and Akhilesh Yadav, to join hands for the 2019 elections and described it as an effort to stop their vote banks from getting empowered.
