Today is also Europe Day, when we celebrate the Schuman Declaration of 9 May 1950.
Scores of public buildings are being ordered to fly the European Union flag to mark the occasion.Funny old world.
Officials will be expected to ensure it remains hoisted for a week from Monday. And those that disobey could be fined.
Incredibly, they are even expected to take a photo of the flag and email it to the European Commission to ensure the rules are being observed.
Schools are also being sent instructions from the European Parliament on how to celebrate Europe Day. Recommendations include holding special assemblies with an EU theme.
