A Nobel-prize winning scientist from Cambridge, whose pioneering work has helped millions of people worldwide to have children, has died at the age of 87.

Sir Robert Edwards was one of two fertility experts whose work at Cambridge University led to the birth of the world's first "test tube baby" Louise Brown in 1978.

Sir Robert was knighted in 2011, a year after receiving the Nobel prize in recognition of his achievements in the development of IVF. His family said he died after a long illness.
