A whistlestop tour of some of Oxford's famous landmarks proved a special challenge for workers at a market research firm.

Nine staff from AC Nielsen, based in London Road, Headington, were set the task of visiting a series of the city's famous buildings and monuments.

The three teams had to decipher clues about the venues and then take pictures of themselves to prove they had completed the team-building exercise.

Global projects executive Ms Munro, who led one of the teams, said: "It was a very well planned exercise -- even though I'm a local, I had to think about where some of the places were."
