MADRID: Two parties supporting Catalan independence have presented a motion in the regional parliament to announce the formal start of secession from Spain and the formation of a new republican state of Catalonia.

The proposition was presented Tuesday by the "Together for Yes" pro-independence alliance that won 62 seats last month in Catalonia's 135-member parliament in September elections, along with the radical leftist CUP party, which won 10 seats.

The parties are calling for the Barcelona-based parliament to vote on the motion urgently, although a regional government has yet to be formed. No date was set for the vote.

The motion calls parliament to pass laws within 30 days that would allow the region push ahead toward a separate constitution, social security system and treasury.
