Trafalgar Square's Fourth Plinth will welcome its latest artwork today when a sculpture by German artist Katharina Fritsch is installed.
The sculpture, chosen from several shortlisted submissions, depicts a bright blue cockerel and will be unveiled by London Mayor Boris Johnson this morning.
The plinth has featured several high profile artworks since 2005, including a marble portrait of disabled artist Alison Lapper, portraying her as heavily pregnant.
