Wimbledon is the oldest of the tennis grand slams, having first been held in 1877. It is the only grass-court grand slam, and it attracts more than half a million spectators, pulling in around £85 million a year.

The usual ways to get tickets are to enter a ballot or to queue up - very early. You can also get a few tickets through Ticketmaster on the day before the event only.

Of the four tennis grand slams, Wimbledon has the most expensive tickets. Although entry into the minor courts can cost a mere £8, you could pay as much as £110 at official ticket prices for an ordinary seat for the men's final. By comparison, the most expensive tickets for the general public at the US Open final are surprisingly cheap at $100 (£61).
