Hundreds of miners are walking to Madrid from all over Spain, some journeys as long as 400km, to protest the massive cuts set to hit the mining industry.
As part of extensive austerity measures, government subsidies for mining are due to be cut by 63%, and will leave 30,000 people out of work.
The march has been met with enormous support, pictures show people lining the streets clapping and holding placards. The Red Cross has been providing the miners with health care, and large tents have been set up along the way with food and water.
Despite strike action now lasting for as long as four weeks, dangerous deminstrations being held under ground, and the march making its way to Madrid, the government has made no concessions.
Due to arrive on July 11, the miners will then form a mass demonstration where thousands are expected to participate.
