>The state-run Anadolu news agency claimed that – with more than 99 per cent of the votes counted – 51 per cent per cent of voters sided with the "Yes" campaign, which would usher in the most radical change to the country's political system in its modern history.
>The vote would replace Turkey's parliamentary democracy with an executive presidency and could see Mr Erdogan stay in power until at least 2029 - as he gain the chance to run for re-election in 2019 and potentially serve two five-year terms. The vote would allow him to re-take control of the ruling Justice and Development party (AKP) that he helped to found. Mr Erdogan spent 11 years as Turkey's Prime Minister - and head of the AKP - before becoming the country's first directly-elected president in August 2014 - a supposedly ceremonial role.
>But the main opposition the Republican People's Party (CHP) said they will demand a recount of up to 40 per cent of the vote, saying that "illegal acts" occurred during the vote and that there were up to 2.5m "problematic ballots". The pro-Kurdish People's Democratic Party (HDP) also claimed they had information that voter fraud was implicated in between three to four per cent of the ballots. Both parties said they would appeal the results.
>The Supreme Election Commission took the unprecedented move to say it would count ballots that had not been stamped by its officials as valid unless they could be proved fraudulent, citing a high number of complaints that its officials at polling stations had failed to stamp them.
