With less than a month to go for the first phase of the Lok Sabha elections, the Congress released its fourth list of 45 candidates on Saturday. Some of the big names on the list are former Madhya Pradesh chief minister Digvijaya Singh, Karti Chidambaram and Danish Ali, who joined the party on Wednesday, but it is also notable for its omissions.Congress' Uttar Pradesh President Ajay Rai will contest against Prime Minister Narendra Modi from Varanasi for the third straight time. Despite naming candidates from Uttar Pradesh for the first time, however, the party has kept the suspense going on the all-important Amethi and Rae Bareli seats.
