Mexican restaurant chain Wahaca has shut nine of its restaurants after a suspected outbreak of norovirus.

Public Health England said it had launched an investigation after 205 staff and 160 members of the public fell ill.

Wahaca, founded by 2005 MasterChef winner Thomasina Miers, said it voluntarily closed the doors to nine sites.

Deborah Turbitt, London deputy director for health protection for PHE, said the source of the outbreak was yet to be determined.
