In pictures: Urban photography competition winners

The results of this year's CBRE Urban Photographer of the Year competition have been announced. The theme was Cities at Work and photographers around the world were asked to record the essence and reality of the working life of a city.

The winning image was taken by Marius Vieth and given the title Mask of Society. It was selected from among 11,500 entries from 79 countries around the world.

Mr Vieth said: "Being named the 2014 CBRE Urban Photographer of the Year is a fantastic achievement. Street photography has been a passion of mine for many years and I knew my Mask of Society image was the perfect shot for the competition's Cities at Work brief. I'm constantly looking for new and interesting angles of urban life and its constantly changing landscape never fails to challenge me."
