The governors of states including Arizona, Arkansas, Delaware, Idaho, Louisiana, Maine, Nevada, New Mexico and North Carolina have all announced that they not will be proceeding to the next stage of reopening.

In England there's a cluster in the city of Leicester. A lawmaker representing the area has called for a local lockdown in the city. Authorities have recorded 866 Covid-19 cases over the past two weeks in Leicester, according to the PA news agency.
