This movement is not carried out by SPA alnone and SPA leaders are not leading the movement on the street and they don't have any strategic plan of how and when to end it. SPA leaders can not decide of their own without consulting Maoists as they announced the 4 days strikes based on the understanding with maoists and elongated it. it is true that without Maoists support and participations, this movement would not have taken this stronger form. people are optimistic this time because they are backed by Maoists this time therefore came to street. it is not just by SPA only. and everybody know Maoists can never accomplish their aim with violence. so Gyane, parties, maoists all recieve the credit for achieving this height and people on the top of it.
