Iraq MPs tied to populist cleric Sadr declare sit-in at parliament

Iraqi lawmakers linked to populist cleric Moqtada al-Sadr have begun an indefinite sit-in at parliament headquarters, two MPs told AFP, amid widespread anti-government protests.

A second wave of demonstrations demanding an end to corruption and an overhaul of the political system have rocked the capital Baghdad and the south since late Thursday.

Sadr has already demanded the current government resign, but on Saturday members of his Saeroon bloc -- parliament's largest with 54 MPs -- said they would escalate.

"We are on our way now to parliament for the sit-in, until the enactment of all reforms the Iraqi people are demanding," said MP Badr al-Zayadi. Saeroon lawmakers were in touch with others to persuade them to join the move, he added.

Zayadi told AFP the bloc had sent an "official request" to Iraqi President Barham Saleh who, according to Iraq's constitution, could then ask parliament to withdraw confidence from the premier.
