What to do in London this week, from the ATP finals to the Lord Mayor's Show - Telegraph.co.uk

ATP World Tour Finals, Greenwich
The ATP is the Association of Tennis Professionals and its annual world tour concludes again this year at London's O2 Arena. As ever, the ATP World Tour Finals sees the world's top eight players in men's tennis round off the season by battling each other to be crowned the definitive tennis champion of 2012. For their trouble there's the chance to pick up a helping of the multimillion-dollar prize fund. With egos to bolster and serious money to be made, the competition is reliably fierce so expect star turns from Novak Djokovic, Andy Murray, Roger Federer, David Ferrer, Tomas Berdych, Jo-Wilfried Tsonga, Janko Tipsarevic and Mardy Fish.
