There was annoyance from the right about The Last Night of the Proms. It appears that they wanted the BBC to censor those waving EU flags. Those flags apparently had been given out free of charge by an organisation, but if a person wanted a Union Flag, they would have had to buy it from vendors outside.
I have to agree with Femi in that patriotism is wanting our great nation to be even better, and it was better in the EU than out of it.
While I would love to re-join the EU, we are never going to get the great deal that we had being in it again. Any referendum held now could probably be won by those wanting to re-join the EU for reasons shared by Gary Lineker.
