He said he was furious with the government for announcing a scheme that was “just hot air”. Heathrow said its test providers were working closely with the DfT to ensure they were granted government approval at the earliest opportunity. A spokesperson for MAG, which owns Manchester, Stansted and East Midlands airports, described the delays to its testing centres as frustrating, saying it had “a provider with global expertise, and the capability to offer the widest possible choice of tests to travellers”. He said the provider, Collinson, had supplied all the necessary information to government and been offering the tests for passengers to satisfy the entry requirements of countries worldwide since the start of the month. He added: “We have been assured the matter will be resolved imminently.”
