It was talking about the Japan deal almost all the way down, but, at the bottom (of course), we get the following information.
What about the EU's existing trade deals?
While it was an EU member, the UK was automatically part of around 40 trade deals which the EU had struck with more than 70 countries. In 2018, these deals represented about 11% of total UK trade.
So far, 19 of these existing deals, covering 50 countries or territories, have been rolled over and will start on 1 January 2021. This represents about 8% of total UK trade, based on 2018 figures.
Nice to know that the success we are having in rolling over trade deals is being reported, front and centre. Maybe because the only country/territory we are having trouble negotiating with is the EU. It may be the largest and it may be the most difficult to resolve, but it is by no means all our fault.
