Invalid Date, A LEADING testing company has been accused of dumping thousands of returned Covid tests in the bin while issuing fit-to-fly certificates to customers. RT Diagnostics has advertised the government-approved test kits for up to £79. 4 4 Action Fraud — which works with the police — said it had received complaints about the firm, run by Labour councillor Faisal Shoukat But a Sun investigation has uncovered claims that many of the tests are simply left lying around in boxes without being processed. The Halifax-based firm is understood to be receiving as many as 10,000 per day as holidaymakers snap up the tests, which legally they need to let them go abroad.
