'It’s an incredible breakthrough' - Mark Pollock stands on his own for first time since paralysis

Mark Pollock has stood on his own for the first time since a fall which left him paralysed in 2010.

The 40-year-old explorer lost his sight aged 22, but went on to become the first blind person to reach the South Pole in 2009.

However, one year after this adventure, he fell from a second-storey window, damaging his spinal cord, and has been confined to a wheelchair ever since.
