City-based astrologer Harikesanallur Venkataraman told IANS: "Modi will certainly become the prime minister."
"The National Democratic Alliance (NDA) will win 333 seats and AIADMK 33. The numbers look fancy, but this is not based on any calculations but my gut feeling," he said.
Venkataraman said a major shake up will take place in the government in December due to changes in the planetary positions.
The Bharatiya Janata Party-led NDA government will be there "but there may be changes at the top leadership", he said.
Suresh Alvar, a numerology hobbyist, told IANS: "Based on the numbers, Tamil Nadu Chief Minister J. Jayalalithaa has all the possibilities of becoming the prime minister."
