Congress, which has never won the seat after 1984 when actor Amitabh Bachchan trounced political heavyweight Hemwati Nandan Bahuguna to clinch the contest by the highest-ever margin of about two lakh votes, is yet to decide on its nominee for 2014's electoral battle.
In the last general elections, when the party appeared to have made a comeback in UP by winning 21 of the 80 Lok Sabha seats in the state, the Congress candidate here finished fourth after polling less than 10 per cent of the votes.
Although Aam Aadmi Party may queer the pitch here for the several players locked in a multi-cornered contest, it is yet to formally announce its candidate for the seat.
The buzz, however, is that AAP founder-member Prashant Bhushan, who has his roots in the city, may try his luck from the historic constituency.
Allahabad, the city where India's first prime minister Jawaharlal Nehru was born, has played a crucial role in the politics of UP and of the country as a whole.
