Does India need an Executive President?

In a provocative article, cartoonist Rajinder Puri (he writes on Constitutional issues also) argues that our Constitution makers in fact envisaged an Executive Presidency. He challenges the first Attorney General of India, M.C.Setalvad's opinion to Prime Minister Jawaharlal Nehru, tendered in the wake of the President Rajendra Prasad's queries, as unsound. A plain reading of Article 74, he suggests, does not strengthen Setalvad's view that the President cannot act without the aid and advice of the Council of Ministers. Any comments?
