Alexis Tsipras has become another austerity politician. Once the expression of the hopes of workers across Europe- Syriza have now joined the austerity consensus. Therefore the announcement that the left of Syriza are splitting to form a new party, Popular Unity, is to be welcomed…It’s vital those who have broken from Tsipras organisationally also make a break with ideas that tie the radical left to a strategy of running capitalism. We have to replace this rotten system- not run it.
