With Chief Minister Manohar Parrikar hospitalised, Goa's main Opposition, the Congress party, submitted a memorandum to Governor Mridula Sinha on Monday, staking claim to form an alternate government.

The move came at a time when the BJP high command has sent three senior leaders - Ram Lal, B L Santhosh and Vinay Puranik - here to meet the state party leaders and allies to take stock of the political situation.
