What is the reason for the formation by Seven Party Alliance?

All the major political parties in the parliament formed a Seven Party Alliance (SPA) and called for a four-day strike in Kathmandu, the country’s capital. This protest soon turned into an indefinite strike in which MAOIST insurgents and various other organisations joined hands. People defied curfew and took to the streets. The security forces found themselves unable to take on more than a lakh people who gathered almost every day to demand restoration of democracy. The number of protesters reached between three and five lakhs on 21 April and they served an ultimatum to the king. The leaders of the movement rejected the half- hearted concessions made by the king. They stuck to their demands for restoration of parliament, power to an all-party government and a new constituent assembly.
