health chiefs admit it's a problem but say they are addressing it. we do recognise there are some difficulties across the country, both in pharmacies and with home testing requests. we do release and are continuing to release test slots for individuals and so they should just keep trying through the day. obviously, as the christmas period subsides, then the testing capacity should be more available to them. we do have good supplies and we will be endeavouring to get those to the right places. the uk health security agency said almost 8 million lateral flow test kits would be supplied to pharmacies by new year's eve. people wanting pcr tests should keep checking the official website as more slots were being made available each day. hugh pym, bbc news. let's speak to professor peter 0penshaw, immunologist at imperial college london and member of the uk vaccine network.
