He said Singh became a Prime Minister on account of certain circumstances which compelled Congress president Sonia Gandhi to withdraw her name from the reckoning.
"He was literally a Prime Minister announced by Sonia ji. He had to function within that limitation.
"....When he addressed the country, he never came out as a leader. The reason for not coming out as a leader was clear. He never wanted to rock the boat. He knew that he was vested with limited power and on all major decisions he had to keep the party and its first family in good humour," Jaitley wrote.
He said Singh has two strong qualities. "Firstly, whenever you discussed a serious subject with the Prime Minister he came out as a man of scholarship. He was what we call to as a 'syana aadmi'."
