Waking up to the news that SYRIZA have won the Greek elections and are about to form a government is a pretty good way to start the week.
And before anybody says it, I do know that Tsipras isn't the messiah and that Greece is not on the brink of constructing a workers' paradise.
But SYRIZA's success does represent the most significant development in Europe since the world economic crisis began. It is not just some re-alignment of the forces of the Far Left - it has given voice to a mass movement that rejects the politics of austerity.
Of course lots of questions remain, and a lot of hard messy work to replicate the same kind of force elsewhere - whether it's Podemos in Spain, the Anti-Austerity Alliance in Ireland ... or TUSC at home.
