All six sitting Bharatiya Janata Party members of Parliament will be re-nominated, party general secretary Mukhtar Abbas Naqvi said on Friday.
"... this may not be so at the all-India level, where some are likely to be dropped," he said after a meeting of the party's Delhi Pradesh election committee.
Delhi has seven Lok Sabha seats.
In the case of the Sadar constituency, from where Rajasthan Governor Madan Lal Khurana had won in 1999, the party has to look for a new candidate, Naqvi said.
Minister of State for Sports and Youth Affairs Vijay Goel, who was elected from Chandni Chowk in the last elections, is said to be keen on shifting to Sadar.
If Goel is shifted, the frontrunner for the Chandni Chowk seat will be former Delhi Mayor Shanti Desai, party sources said.
