A third baby is suspected of having E.coli at a hospital in Wales where two infants have already died from the disease, health chiefs confirmed late on Friday night.

The maternity unit at Singleton Hospital in Swansea has been restricted to full-term babies following the two earlier deaths. The latest case involves a baby who was a patient in the past month in the neonatal unit at the hospital.

"A third case of ESBL E.coli cross-infection is unfortunately suspected at the maternity/neonatal unit at Singleton Hospital," a spokeswoman said.

Investigations are continuing into the cause of the infection and into how the E.coli bug was transmitted.
