Sir Paul Smith: Fashion designer 'fighting for design'

The British fashion designer Sir Paul Smith's contribution to fashion is to be recognised in an exhibition at the Design Museum in London.

The 67-year-old designer opened his first shop in 1970 in Nottingham and has gone on to sell clothes in 74 countries around the world.

But Sir Paul said it is a struggle for designers to get the recognition they deserve.
