Turkey's prime minister Ahmet Davutoglu has announced his resignation.

Davutoglu, who has clashed with President Recep Tayyip Erdogan, said he was stepping down as leader of Turkey's ruling AK Party following a meeting with party executives.

The party will hold an emergency convention on May 22 to select a new party leader, who will also replace the premier.

"I would never consider running as chairman if there is no consensus," Davutoglu said.

"Under these conditions, I am not considering standing as a candidate at the upcoming extraordinary congress."

Davutoglu said he would continue to be a member of party.

"I feel no reproach, anger or resentment against anyone," he said.

"No one has ever heard any word from me against our president and never will."

Davutoglu's resignation will pave the way for Erdogan to pursue a tighter grip on power.

Divisions between the Davutoglu and Erdogan camps first spilled into the open over Turkey's conflict Kurdish militants in the south-east.

On Monday, a brawl broke out in Turkey's parliament between members of the ruling AK Party and the pro-Kurdish opposition party HDP over controversial legislation that could see some lawmakers investigated on terrorism charges.
