Frustrated London council chiefs have blamed the failure of the Government’s “world beating” test and trace system on its early refusal to involve local authorities.
New figures have shown the £12 billion NHS project is still failing to reach 40 per cent of close contacts of people testing positive six months after it was launched.
Senior town hall bosses said the initial decision to create a centralised system using call centres to contact people hundreds of miles away fatally undermined its effectiveness.
Local authorities are now more involved in test and trace but critics say the earlier decision to overlook them contributed to the second wave of infections this autumn.
