hello sir,
though your posted question has a direct answer that the members of parliament should not hold office of profit, it should be essential to further point out that they can hold any office, but should not expect any profit from it. to put it more bluntly, even if a particular position is held as office of profit, when a parliament member is elected/appointed for such position, he/she should not be Entitled to get the actual profit which otherwise have been entitled.
