If successful the campaign will aim to replace Turkey's parliamentary democracy, with an all-powerful presidency. Erdogan saying it's a move necessary, to confront the security and political challenges Turkey faces. Reuter's Nick says regardless of the outcome, Erdogan will continue to seek more power.>> Well this is in some ways the ultimate test of Erdogan's popularity.
If the result is a no vote, he's unlikely to simply back down and accept that he can't continue ruling, in the way that he has been. What we would probably see would be an early election. An attempt to strengthen the power of the ruling party in parliament. And then potentially, another referendum further down the line.
>> Opponents say a yes vote would be disastrous, and mark a step towards even greater authoritarianism. In a country where 40,000 people were arrested and 120,000 sacked or suspended from their jobs, in a crackdown following a failed coup attempt against the President last July. Despite being criticized by the EU and western leaders for his tough response, Erdogan shows no sign of slowing down the purge.
At a rally Saturday, he told supporters that the country must finish what it started, referring to the crackdown. Some 55 million people are eligible to vote on Sunday. If the Yes campaign is successful, a package of 18 amendments would abolish the office of prime minister, give the president authority to drop the budget and declare a state of emergency.
Whatever the outcome, Turkey is and may well remain at a crossroads.>>
