Just outside the Tower of London, were these two RNLI launches. On an otherwise grey day, the bright orange boats provided a splash of colour on the river.

Apologies to the Linux users out there (like myself) who have to put up with an error message when loading that Tower of London page – just click OK and the page loads OK. I have reported the error to the site’s webmaster and PR person, but I doubt anything will happen to fix it.
