On Monday, Boris Johnson will "carefully but irrevocably bring a pint of beer to his lips". The British prime minister said this a few days ago when he announced the next step in opening the hard lockdown. The prime minister is in a celebratory mood. Pace of vaccination, economic recovery, consumer confidence - all indicators are up in the UK, unlike the continent. But wasn't there what? Right, the Brexit. Until the outbreak of the Covid pandemic, it seems to have been almost forgotten in the current mood of optimism. It has been a reality for 100 days, with the end of the transition period on January 1, 2021.
