Every year 350,000 women die in childbirth across the globe, with the majority of the deaths taking place in developing countries, volunteer organisation VSO said.VSO's UK director, Angela Salt, said many lives could be saved if health workers in developing countries were given better training.

British pilot David Simpson, who was jailed in Africa on suspicion of mass murder after he discovered the victims of an apparent massacre is back in the UK after being cleared of all charges, William Hague said.
The Foreign Secretary welcomed the return of Mr Simpson who was arrested in the Central African Republic five months ago after he stumbled upon a gruesome scene in the bush involving 13 bodies and informing local officials.
The 24-year-old pilot - who worked for a Swedish safari company - was held in Ngaragba Central Prison in the capital, Bangui, before being put under temporary house arrest after the jail was stormed by rioters and destroyed earlier this month.
Mr Hague said: "I am delighted to confirm that David Simpson is now back in the UK. Government Ministers and officials have worked hard on his behalf. I raised the case with Central African Republic Foreign Minister Gambi in August and am pleased that his case has now been resolved.
"Foreign Office Minister for Africa, Mark Simmonds, has spoken to Mr Simpson's family to pass on his and my best wishes."
