Some more details on German leader's planned talks with President Hollande
Chancellor Angela Merkel's spokesman Steffen Seibert has released a statement.
"The talks with the French president from 6:30 p.m. (1630 GMT), and over dinner will be about a common assessment of the situation after the Greek referendum and the continuation of the close German-French cooperation on this subject."
Greece's ANT TV estimates that the proportion of voters taking part in the referendum was close to 65%. If confirmed that would be slightly higher than the January 2015 election that Syriza won. Turnout then was just under 64%.

Quote MessageThis is the climax of the Greek debt story that we have been talking about for five years
Macro-economist Alberto Gallo has come up with this interesting look at what could happen in the event of a 'Yes' or 'No' vote.
The BBC's Europe correspondent Chris Morris explains...
"There are going to be a lot of numbers flying around in the next few hours - we are going to have to be very careful.
"Several polling companies have undertaken telephone polls - these are not exit polls, not people being asked how they voted as they leave polling stations.
"So a couple of companies we have spoken to have contacted telephone in fairly small samples - and both of those polls put the 'No' campaign very narrowly ahead."
Reuters: Syriza parliamentary spokesman says opinion poll results allow government to move forward quickly and seal deal with creditors .
3 opinion polls show Greek referendum result will be close, but likely to be won by "No" vote.
Pollster GPO estimates that the No vote has a lead of 51.5% to 48.5%. Similar margins are being predicted on Greek TV
Although the first estimates will come in shortly, a first indication of the results won't emerge until 19:00 BST. According to Mega TV, a proper indication will be clear only once results are in from 10% of polling stations. Even then, there will be a margin of error.
It's important to note that there are no traditional exit polls. Instead phone polling is being conducted.
Voting in the Greek referendum has finished. The first exit polls are expected soon.

I lived in Thessaloniki and Athens for ten years until 2000, and I strongly support the 'no' vote. I believe Greece may well be better off with the drachma; More tourists would come as it would be cheaper, which is Greece's main income; and once things had settled down salaries would find their level. I left before the Euro, but I would not have been able to survive had I stayed
