The plan to appoint Pasir Salak MP Tajuddin Abdul Rahman as a diplomat is to reward his strong backing for Umno vice-president Ismail Sabri Yaakob, who emerged victorious in the prime ministerial race after Bersatu president Muhyiddin Yassin was ousted from the top job.<br /><br />An Umno source who is close to Tajuddin told Malaysiakini that another key figure who also backed Ismail Sabri was Nazri Abdul Aziz, who is also tipped for an ambassador position.
