"GSK has a proud heritage in India. Today's announcement is a further demonstration of our long- term commitment to the country having increased our holding in our consumer business earlier this year and more recently committed to a significant manufacturing investment."
The transaction will be funded through GSK's existing cash resources, will be earnings neutral for the first year and accretive thereafter and will not impact expectations for the Group's long-term share buyback programme.
