A FOOD festival was “invaded” by striking museum workers on Saturday as a bitter dispute over weekend working benefits continued.

Workers from all of the National Museum of Wales’s sites, including former miners employed at the Big Pit coalmining museum in Torfaen, marched to the St Fagans National History Museum in Cardiff, where guests were enjoying fancy grub.

Bosses plan to strip workers, who are organised by public-sector union PCS, of “premium payments” for working weekends and bank holidays.

Thousands of visitors looked on as the protesters stormed the festival following a rally supported by Cardiff Trades Council, which was addressed by Welsh Labour AM Lynne Neagle.

Earlier in the morning, museum pickets had been supported by striking bus drivers with transport union RMT.
