Goa [Images] Governor S C Jamir has asked Chief Minister Digamber Kamat to have a floor test on Monday to prove his government's majority in the assembly.

The political crisis in Goa reached the Rashtrapati Bhavan [Images] with the Bharatiya Janata Party parading 20 of its supporting MLAs before President Pratibha Patil [Images] in what is seen as her first brush with the rough and tumble of politics.

Led by BJP chief Rajnath Singh, the 20 MLAs, including Pandurang and Ramkrishna Dhavalikar of the Maharashtrawadi Gomantak Party and Churchill Alemao of the Save Goa Front trooped before Patil with demand to ensure a sitting of the state assembly on Monday.

"The Goa government has been reduced to minority and has deliberately skipped the sitting of the assembly on Friday," Leader of the Opposition in Goa assembly Manohar Parrikar [Images] told reporters after meeting Patil.

"The Goa assembly must sit on Monday, July 30 without fail," Singh said in a memorandum submitted to the President.

"The President told the MLAs that Goa Governor (S C Jamir) will uphold the Constitution," a Rashtrapati Bhawan spokesman said.
