He said on Friday that it was the prime minister’s “prerogative to decide which minister will get what portfolio”.
“It’s her constitutional responsibility. This is an ongoing process.”
Sengupta, a member of Awami League Advisory Council, was speaking at a discussion on current political situation at Institution of Engineers, Bangladesh auditorium in Dhaka.
He said: “There is no reason to raise a hullabaloo over (Syed Ashraf getting relieved of the portfolio).”
Ashraf lost his job as LGRD and cooperatives minister on Thursday but remains as a member of the Cabinet without any portfolio.
Sengupta said: “Syed Ashraf is a politician from head to toe. He has been pursuing politics from his student days. He is a tested comrade and a member of a martyr’s family.
“I don’t think it is a big deal for him to have a portfolio or to be a minister.”
Sengupta, who had also lost railways portfolio during the 2009-14 Awami League-led government, said Ashraf would have to contribute to the national politics irrespective of his political position.
“So we have to keep confidence in our indisputable leader, the prime minister. Whatever has happened has happened in the interest of the country, party and democracy. There is nothing more to say here.
He said: “His (Ashraf’s) honesty, sincerity and patriotism are beyond question. He is an honest and polite politician.”
