31 January 2020 - After more than three years of Brexit talks, deals and political wrangling, the United Kingdom will officially leave the European Union at 11 pm GMT today.

MAESTrO Database will be monitoring this situation closely. We will collect market access data post-Brexit and compare them with the data we hold pre-Brexit. Sadly, it is not possible to conduct a randomised trial here.
