Mexico Congress oil row deepens

Leftist politicians in Mexico who last week stormed both houses of Congress have vowed to remain in protest at planned reform of the state oil giant.

The government says the Pemex oil company needs outside investment to boost falling production and increase exploration for new reserves.

But the protesting deputies and senators argue that this will lead to a creeping privatisation of Pemex.

The protesters want a broad debate on Pemex, in state hands for 70 years.
