London, Sep 26 (TIWN) London Mayor Sadiq Khan has urged UK Prime Minister Boris Johnson to ban household visits immediately, claiming the Covid-19 situation in the capital city was much worse than first believed, the media reported on Saturday.

Speaking to the Guardian, Khan warned that a 43 per cent fall in testing across the city has masked the severity of the second Covid-19 wave, saying the real infection rate was not far behind hotspots in the north-east, reports the Metro newspaper.

He accused the government of "pointing the finger at the public" for the spike in new cases and "not learning lessons" from when the virus initially hit the country earlier this year.
