Sweet potato island and a black cat shortlisted for London’s fourth plinth

Public encouraged to comment on seven artists’ proposals for ephemeral pedestal in Trafalgar Square

A sweet potato island; a hollow, lifesized person on a horse cast in slime-green resin; and a golden bronze sculpture of a woman whose features have been amalgamated are among the shortlisted ideas for the next fourth plinth commission in Trafalgar Square.

Organisers of the contemporary art installation announced on Monday seven shortlisted artists for the project: Chila Kumari Singh Burman, Gabriel Chaile, Ruth Ewan, Thomas J Price, Veronica Ryan, Tschabalala Self and Andra Ursuţa.
