The UK government has confirmed they are looking at relaxing the two-metre social distancing rule.
This comes after the Prime Minister asked scientists to to see if it can be reduced in an effort to help public transport and the hospitality sector.
But Health Secretary Matt Hancock said being one metre away from someone for one minute has the same risk of transmission as being two metres away from someone for fifteen minutes.
Asked about whether the two-metre social distancing rule will be amended, Mr Hancock told LBC: "The scientists are going to look at it.
"What doesn't change is the science, which is that if you are closer then you are more likely to transmit.
"The scientists tell me that they reckon at one metre, for one minute, that has the same risk of transmission as being at two minutes for 15 minutes.
The 2 metre social distancing rule is still in force across the UK.
