Christmas is coming a little early on the Thames with Santa swapping his traditional sleigh for a handy speedboat to switch on the festive lights at St Katharine’s by the Tower.

Father Christmas is bringing his yuletide cheer and twinkling lights on November 21, as he's done in previous years.

He arrives at St Katharine marina to throw the switch to turn the ancient heritage docks into a floating winter wonderland.

The docks are usually loaded with festive activities and quayside activities over Christmas.

This year's entertainment includes a carols performed by children from St Peter's school choir in Wapping and grown-ups from the City of London's chamber choir.

Mulled wine, mince pies and hot chocolate are being served to keep toasty by the waterside.

A "Christmas duck hunt" is also being laid out where players have to seek out one of the 25 ducks hidden around the docks.
