Rahul Gandhi will lead the Congress campaign for the general election, but his mother and party president Sonia Gandhi has decided he will not be the party's prime ministerial candidate. br br Her decision was taken at this evening's meeting of the Congress Working Committee - the party's senior-most leaders including Mr Gandhi who is Vice-President. br br Many in the group urged that the 43-year-old formally run for prime minister. But Mrs Gandhi said the Congress traditionally does not name a candidate before voting is held and that Mr Gandhi will serve as the campaign chief, a decision that was then endorsed by the group.
