Viagra maker Pfizer denies Brexit link to two UK site closures

US drugs company Pfizer has announced plans to close two sites in the UK, putting 370 jobs at risk. The maker of Viagra said the decision was made following a review of its global supply network - insisting there was not a link with the UK's vote to leave the EU. The pharmaceutical firm said the Hospira UK (Aseptic Services) Compounding site in north London, where it employs 100 people, would shut in mid-2017.
