Coronavirus deaths in the UK have now exceeded 100,000
Tuesday saw 1,631 deaths recorded across the UK, bringing the death toll to 100,162.
It is the first country in Europe to surpass this number.
Prime Minister Boris Johnson will be addressing the UK at 5pm on Tuesday.
In a statement, Sir Keir said: "This is a national tragedy and a terrible reminder of all that we have lost as a country.
"We must never become numb to these numbers or treat them as just statistics. Every death is a loved one, a friend, a neighbour, a partner or a colleague. It is an empty chair at the dinner table.
"To all those that are mourning, we must promise to learn the lessons of what went wrong and build a more resilient country. That day will come and we will get there together.”
