THE famous Mozambican socialist leader Samora Machel once said: “International solidarity is not an act of charity — it is an act of unity between allies fighting on different terrains toward the same objective. The foremost of these objectives is to aid the development of humanity to the highest level possible.”

As the world continues to struggle through a period of heightened tension and conflict, Liberation once again reasserts our key values of peace, democracy and internationalism on May Day 2023. May Day reminds us that it is only solidarity between the people of all countries which will overcome conflict.

As ever, the common interests of working people across the world underline that there is more that unites the international working class than divides them.
