ANKARA/ISTANBUL (Reuters) - Campaigning has not officially started, but a string of video "selfies" by the likes of sports stars, actors and cabinet ministers has already launched a divisive debate on plans that would hand Turkish President Tayyip Erdogan sweeping new powers.
His supporters see the move to replace Turkey's parliamentary democracy with an all-powerful presidency as a guarantee of stability at a time of turmoil. Opponents fear a lurch towards authoritarianism if an April referendum approves the change.
In a country where mainstream news channels are saturated by Erdogan's appearances and speeches by government ministers, and where political demonstrations are tightly restricted, the battle for votes is increasingly being waged online.
