Elsewhere on ITV News, Robert addressed Mr Johnson’s announcement into the public inquiry on Covid.
He suggested that the Prime Minister will be under scrutiny over lockdown, PPE shortages and the protection of the elderly in care homes.
Robert commented: “Now, inevitably this is complex and will go on for a long time. Probably, years.
“About the only thing going for the Prime Minister in this process is it is very, very unlikely to report before the next General Election.
“But let’s be under no illusion, simply giving evidence the Prime Minister himself could be interrogated under oath for days. It will not be comfortable for the Prime Minister.”
