I'll vote for the institution of monarchy, a ceremonial one with sociocultural significance / and a symbol of national unity but with no political power. This is necessary I think, simply because I can't imagine Girija / Prachanda or anyone else at Indrajatra 'or' Bhotojatra celebrations / Fulpaati 'or' Shree Panchami at Basantapur 'or' lot of other cultural / historical customs and rituals which are deeply ingrained in the lives the nepalese. And I can't imagine the picture of Prachanda smiling in front of the living goddess 'Kumari' 'or' Girija exchanging 'Khadga' on 'khadga jatra', lol. However, this is just the views as per my sentiments. Others may differ in their opinions.
