A new superbug that is resistant to even the most powerful antibiotics has entered UK hospitals, experts warn.
They say bacteria that make an enzyme called NDM-1 have travelled back with NHS patients who went abroad to countries like India and Pakistan for treatments such as cosmetic surgery.
Although there have only been about 50 cases identified in the UK so far, scientists fear it will go global.
Tight surveillance and new drugs are needed says Lancet Infectious Diseases.
