Bolivia assembly approves charter

More than one-third of assembly members boycotted the vote

Bolivians will now have a chance to vote on the document in a national referendum next year.

The 164 deputies present out of the total of 255 took 13 hours to vote on each article of the new constitution.

The new charter would give greater autonomy to Bolivia's indigenous people and eliminate presidential term limits.

The draft constitution has proved contentious in Bolivia, with strikes and protests against it.

At least three people have been killed in clashes between protesters and police.

President Evo Morales proposed on Wednesday that he step down if "No" votes in the upcoming referendum exceed the vote which elected him in December 2005 - 54%.
