Battle to secure the Karhal seat, which goes to polls on February 20, intensified on the second last day of campaigning as the key candidate and, Samajwadi Party chief Akhilesh Yadav brought his 83-year-old father Mulayam Singh Yadav popularly called Netaji on the campaign trail with him. The ageing and ailing SP patriarch came to Karhal from Lucknow. He was accompanied by the extended Yadav family including brothers Shivpal Yadav and Ram Gopal Yadav. Mulayam made a brief appeal seeking votes for his son and promised development. Mulayam’s last-minute effort of an appearance for his son exposed the chinks in Akhilesh’s armour. This was simply explained by Union Home Minister Amit Shah, who was campaigning in Karhal for BJP candidate and Union Minister of State Prof SP Singh Baghel. Taking a swipe at Akhilesh for dragging his father to campaign for him, Shah said it exposed the weakness of the Samajwadi camp. Incidentally, Baghel was a PSO to Mulayam and was brought into politics by Netaji himself. In the past few elections, Karhal has traditionally been a SP seat. Though both Akhilesh and Baghel are now Lok Sabha MPs, the BJP has made winning the seat a prestige issue. “If lotus blooms here in Karhal it will be equal to getting 300 seats in UP, ” thundered Shah.
