Climate change protesters glue themselves to masterpiece in London's National Gallery

Two climate change protesters have glued themselves to the frame of John Constable’s masterpiece The Hay Wain.
The Just Stop Oil (JSO) protesters also attached their own image of “an apocalyptic vision of the future” of the landscape, on three large sheets of paper, featuring an old car dumped in front of the Mill and the Hay Wain cart carrying an old washing machine.
