The newly elected opposition majority voted in Allup as National Assembly president yesterday.
The legislative session that starts tomorrow will represent the first time opponents of Venezuela's socialist administration have had control of any government institution in more than a decade.
Allup won the leadership vote with the help of opposition hard-liners who favour street demonstrations and direct confrontation with the administration.
He beat more moderate lawmaker Julio Borges, whose Justice First party advocates a policy of negotiation and a focus on the ballot box.
