E Sreedharan, the legendary "Metro Man" of India, is set to join the BJP months ahead of polls in Kerala. The 88-year-old is likely to join the party during its Vijay Yatra in Kerala from Sunday and may also contest the Kerala election, due by May, although there are questions about the BJP's cut-off point of 75 years for elections, applied previously to veterans like LK Advani and Murli Manohar Joshi.
