Mr Hancock said: 'This is an important milestone, and it represents further progress in our national testing programme'.
The government has announced the start of trials for a new test to see if people have coronavirus, with results processed on site within 20 minutes.

Johnson previously described antibody tests as a "game-changer" in the response to the virus.

It has also been noted that we are not yet clear on how much protection antibodies give us against the virus.
Abbott's data has so far shown that the test, which can be used at the point of care and produces results in minutes, finds positive cases of COVID-19 almost 95% of the time when compared with two other tests performed in laboratories.
CDC Issues New Guidance on Coronavirus on Surfaces
The agency also estimates that 40% of coronavirus transmission is occurring before people actually feel sick. Before, researchers originally thought the virus could live on some surfaces for up to three days.
