LONDON (Reuters) – Britain must step up its testing and tracking to help tackle the coronavirus crisis, lawmakers said on Tuesday, criticising the government for dropping a programme to check for COVID-19 in March and not moving fast enough to build it up.

In a letter to Prime Minister Boris Johnson, Greg Clark, chairman of the parliamentary science and technology committee, listed some of their findings, suggesting there was a lack of transparency over scientific advice and decisions on testing.

Johnson, who says the government is following scientific advice in its response to the outbreak, has come under fire for being slow on testing, for failing to provide protective equipment and for sacrificing care homes.

His spokesman said ministers had set out that they recognised the need to increase testing capacity and “that is what we have been doing … and we’re now in the position where we can carry out well in excess of 100,000 tests a day”.

But the committee said in the letter that the government must learn the lessons from the slowness on testing.

“One of the most significant problems of the handling of the pandemic to date in the United Kingdom has been the lack of capacity to test people to determine whether they have COVID-19,” Clark wrote in the letter.

“Very low numbers of people were being tested well into March, with the number of tests actually falling at a critical time to 1,215 on March 10.”

He also said a decision to concentrate testing in a limited number of laboratories and expand it gradually rather than boosting capacity by using other laboratories was “one of the most consequential made during this crisis”.
