(disclosure: UPS/UPS International is a client of Edelman, the P.R. firm where I work.)
More specifically, UPS is now London 2012's "5th Tier Two Supporter and 22nd domestic commercial sponsor overall."A sampling of headlines from both sides of The Pond include the hometown Atlanta Journal-Constitution as well as Reuters London and Associated Press reports.
The UPS U.K. site also provides a bit of detail. Jolly good show!
