This is a photo Alexis Tsipras releasing a bird. The photo was taken on the day of the Epiphany (6/1/15). The bird symbolises the Holy Spirit.
SYRIZA is often attacked by Ne Democracy MPs of being a bunch of atheists which is why the photo quickly made a certain impression. During the past few months SYRIZA has been trying to play down these (otherwise non-political) accusations by visiting monasteries, religious leaders and even the Pope. Outgoing PM Antonis Samaras has even said some days ago that if SYRIZA wins the religious icons that decorate almost every public building, from ministries to schools, will be removed.
The photo of Tsipras releasing the bird was used as a poster for an online event where Tsipras answered questions via Twitter.
And this is a cartoon by Dimitris Hantzopoulos (TA NEA daily). It combines all of the above with Hitchcock’s legendary movie “The Birds”.
