A Game of Thrones actor, a TV chef and a duchess were among those who posed with a fancy dress pig outside Parliament to protest against the opening of a new farm.
The proposed pig farm could be opened near Limavady in Northern Ireland, which forms part of the backdrop for the Game of Thrones television series.
Protesters included Jerome Flynn, who played Bronn in the award-winning fantasy, TV chef Gizzi Erskine and the Duchess of Beaufort Tracy Worcester.
Other attendees included actor Ciaran McMenamin, former Men Behaving Badly star Leslie Ash and cookery author Melissa Hemsley.
The campaign, which is being supported by groups Farms Not Factories and Friends of the Earth Northern Ireland, is being backed by Conservative MP Zac Goldsmith, who was also in attendance.
More than 17,500 people objected to the proposals or signed a petition opposing the opening of the farm and the planning application has been stalled, according to Farms Not Factories.
