Adding a new dimension to the death of Punjab cooperation minister Capt Kanwaljit Singh in a road accident in Kharar last month, former Punjab chief minister and Punjab Congress Campaign Committee head Capt Amarinder Singh raised several doubts on Tuesday over the manner in which the minister died.

"The manner in which the accident occurred raises several suspicions in a reasonable mind," said Amarinder while addressing a public rally in support of his wife and sitting MP Preneet Kaur, who is seeking re-election from Patiala, in Zirakpur on Tuesday.

Calling Kanwaljit as "very honest" leader, the senior Congress leader said the Akali leadership was feeling insecure in the presence of Kanwaljit who held a massive base in the public across the state. "Sensing trouble to the future of top Akali leaders, a conspiracy seemed to have been hatched to eliminate Kanwaljit," said Amarinder. He promised to hold a high-level probe into the incident if the Congress was voted to power in Punjab.
