Greek Prime Minister Alexis Tsipras is all set to resign, officials have said - paving the way for early elections on 20 September. The Syriza leader is set to make a televised address to the nation tonight, where he will make his intentions clear. Because Tsipras’ government has been in power for less than 12 months, opposition parties would be given three days to try and form a government - but if they fail, a general election will be called by the president.
