Prime Minister Alexis Tsipras is to unveil his proposals for a review of the Greek Constitution on Monday evening in a speech from the garden of the Presidential Mansion.
On Sunday evening, party leaders joined Tsipras and President Prokopis Pavlopoulos in the presidential gardens for a function marking the anniversary of the restoration of parliamentary democracy in Greece following the fall of the military dictatorship.
Although the messages expressed by party leaders on Sunday night were ostensibly about unity there were said to be tensions between the leaders following several days of vehement debate in Parliament last week culminating in a vote on changing the electoral law.
As for Tsipras's speech on Monday night, sources close to the premier did not rule out the possibility of some surprises.
Another tense session in Parliament is expected on Tuesday when a discussion is set to begin regarding the creation of an investigative committee to probe the actions of the government in the first six months of 2015 when the leftist-led government clashed with the country's creditors, led Greece to the brink of a Eurozone exit and imposed capital controls on Greek banks.
