The two men join hundreds of others who are taking part in a number of record attempts across the world to celebrate the occasion.

The annual broke a record of its own in 2004 when it became the world's best-selling copyright book. Guinness World Record Day was set up to commemorate the date.

Mr Kösen, 31, from Ankara, Turkey, became the world's tallest living man in 2009, when he took the title from 63-year-old Xi Shun, from China, who measured 7 ft 8.95 ins. in 2005.
