Police have escorted BA boss Willie Walsh from the Acas building in London as protestors stormed the building where talks with Unite were taking place.
The Socialist Worker protest demanding a stop to cuts and a right to work saw around 100 people mount a noisy protest outside the building.
Some demonstrators were said to have broken in through a side entrance forcing the talks to be suspended.
BA had hoped to reach an agreement with BA over planned strike action on Monday. Talks are set to resume tomorrow in a secret venue to avoid a repeat of tonight’s scenes.
