UNIONS accused Boris Johnson of shifting responsibility for workers’ safety away from his government today after he announced it would be up to bosses to see a return to workplaces in two weeks’ time.

The PM’s easing of work-from-home guidance appears to contradict recommendations from his chief scientific adviser Sir Patrick Vallance, who has said there was “absolutely no reason” to change previous advice.

Chief medical officer for England Professor Chris Whitty has also warned that social distancing measures will need to stay in place until the discovery of a Covid-19 vaccine or highly effective treatment.
