Why do we need a minister without portfolio?

Kazi Mizanur Rahman, Gulshan 2, Dhaka
Can we really afford to employ a minister without portfolio in the cabinet of our prime minister? Does not it look like a poor nation spending lavishly? A minister in the cabinet has to be paid a handsome salary, needs a Pajero, a house and several men for security and household purposes -- all of these at public expense. In a country where millions of people cannot manage three basic meals a day, how can the government spend that much for a minister who is not required in the cabinet? In Bangladesh there are highly educated and conscious people who are able to understand the wrong decisions taken by the government but. Bur government doesn't bother at all.
