LONDON, September 22 - Covid-19 is "returning to spread exponentially, as we see" from the numbers of countries "such as Spain or France", and that is why the United Kingdom must adopt the new restrictions announced today to "curb the virus now". Prime Minister Boris Johnson said in a televised address to the nation, insisting that he wanted to "do everything possible to avoid a new national lockdown". The premier described it as "unrealistic" to think that the contagion of young people is without consequences, since it ends "inevitably" by involving other age groups. He then warned the population to show "discipline". (HANDLE).
