Asked about the possibility of Modi contesting from a constituency in Uttar Pradesh, he said the decision has to be taken by the party's parliamentary board and that nothing was final yet.
Shah said feedback on probable candidates was being collected and would soon be considered by the parliamentary board.
The BJP will hold two rallies at Gorakhpur (Jan 23) and Meerut (Feb 2) and another rally later in Lucknow.
The party currently holds 10 Lok Sabha seats from Uttar Pradesh. At the peak of the Ram Janmabhoomi movement in the 1990s, the party had won 57 seats.
