Effects of thalidomide 'were horrific'

It is more than fifty years since the drug Thalidomide was prescribed to pregnant women around the world, leaving as many as 100,000 babies born deformed.

The drug, sold in the 1950s as a cure for morning sickness, was withdrawn in 1961.

David Mason, whose daughter Louise was born without arms or legs, led the campaign against the drug.

He told the Today programme that the effects of Thalidomide "were horrific".
