Toppling statues: When should they come down?

The violent clashes in Charlottesville, Virginia - which left one woman dead and many others injured - have intensified the debate about the hundreds of statues and plaques commemorating Confederate leaders right across the United States.

So, what is the best way to remember troubled history? Should monuments be re-named, removed or ignored? Does pushing for more removals risk inflaming the identity politics at the root of the clashes in Charlottesville?

Plus - what parallels are there with the UK, where events in the US have renewed debate about the many monuments to historical figures in Britain? Owen Bennett-Jones and a panel of guests debate what should be done about statues that offend.
