The Barisan Nasional Backbenchers Club (BNBBC) wants the Home Ministry to thoroughly investigate last Saturday's road crash which claimed the life of Batu Sapi MP Edmund Chong Ket Wah.
Its chairman Tiong King Sing, who led a BNBBC group to pay their last respects to Chong in Kota Kinabalu today, said they were not convinced by the many explanations on the cause of the crash.
