At a loose end in London Sunday 27th?

[SteveC]

The King's Army of the English Civil War Society will be commemorating the execution of Charles I with their customary march down the Mall, parade on Horseguards and march back up the Mall on Sunday morning. The march usually starts around eleven.

It is a little self-indulgent in some ways, but who's going to turn down the chance to have any sort of event in that location?

Come along - it's a chance for some decent photos if nothing else!
