The banner when translated means “The people are mightier than a lord”, and “change begins in the kitchen, not the boardroom”.
Activists were seen eating food out of Tupperware and drinking tea out of flasks.
The wing of the Palace of Holyroodhouse impacted by the sit in has been temporarily closed to the public.
