Warsaw - Thousands of Solidarity labour union members marched in the capital on Friday demanding better wages, better retirement pensions and improved labour laws.

Workers came from all over Poland to gather in Warsaw's Pilsudski Square and march across the city towards Prime Minister Donald Tusk's office.

There, they were slated to release balloons inscribed with Tusk's quotes to symbolize his "flyaway" election promises. The workers also gathered coins for Tusk's symbolic "early retirement."

At the head of the march, workers pushed shopping carts filled with a few staple items they claim the average Polish old age pensioner or minimum wage worker can afford.

The march comes near the 28th anniversary on Sunday of a historic agreement between communist authorities to legally recognize the labor union.
