A new Covid variant that is a hybrid of the Omicron and Delta strains is officially being monitored by health chiefs.
The new variant - labelled Deltacron - has been identified in a UK patient and was named by the UK Health Security Agency (UKHSA) in its weekly "variants in monitoring" list.
The new variant is believed to have evolved in a patient who caught both the Omicron and Delta variants at the same time.
