Turkey edged closer to adopting a constitutional bill extending President Tayyip Erdogan's powers overnight, with parliament approving four more articles of a reform.
Erdogan, who could rule the European Union candidate country until 2029 if the legislation is passed, says it will provide stability at a time of turmoil and prevent a return to the fragile coalitions of the past.
During the evening debate an independent lawmaker, Aylin Nazliaka, handcuffed herself to the podium in protest against the stronger presidency, triggering a scuffle between MPs of the ruling AK Party and opposition parties.
The reform would enable the president to issue decrees, declare emergency rule, appoint ministers and top state officials and dissolve parliament - powers that the two main opposition parties say strip away balances to Erdogan's power.
With the adoption of the latest four articles overnight, the assembly has now approved 11 articles in the second round of voting. It is on track to pass the remaining seven articles and vote on the package as a whole on Friday night, Reuters reported.
Providing it garners the support of at least 330 deputies in the 550-member assembly in the remaining votes, the legislation will go to a referendum, expected in the spring.
