LONDON, Jan 16 (Reuters) - Wimbledon's ‌plans to expand the grounds for the world's oldest ‌and most prestigious Grand Slam tennis tournament were back in ‌court on Friday, as campaigners again seek to block the project.

The All England Lawn Tennis and Croquet Club wants to treble the size of its main ‍site, which has been home to the ‍Championships since 1877, in a ‌200 million-pound ($267.9 million) project which would feature 39 new courts.
