My hon. Friend is absolutely right to raise this. As he will know, phase 1 of the WHO-convened covid-19 origins study was always meant to be the beginning of the process, not the end. We are working with our international partners to support the timely, transparent, evidence-based and expert-led phase 2 study, including, as recommended by the experts report, in China. World Health Organisation director general Tedros has said that “all hypotheses remain open”, and further data and studies are required. As such, we expect all WHO member states to live up to their responsibilities and co-operate with phase 2.
