Neena Bhati, head of campaigns at consumer body Which?, told MPs on the House of Commons transport committee there had been progress in removing lateral flow test providers who were not delivering good service, from the government list.
“But we would like to see more checks at the beginning, rather than when consumers have already been impacted by them,” she added.

“The recommendations by the CMA (Competition & Markets Authority) need to be implemented,” she added.
