The solution agreed in the Gibraltar treaty guaranteeing frontier fluidity while stopping short of full EU free movement was “worth evangelising”, Chief Minister Fabian Picardo said in a letter to the Financial Times on Wednesday. “In the days of lengthy queues at EU borders (and with Etias visas to come), frontier fluidity without the problem of potential immigration from the EU makes our treaty one worth evangelising.” In his column published on Sunday, Mr Sandbu said achieving an open border for goods and people were “wonderful objectives”, adding the Gibraltar treaty should show Mr Burnham that “a softer Brexit is the only option”. “From Theresa May to Keir Starmer, both of whom proposed even more UK-wide alignment on a single market for goods to reduce frictions, seeking closer ties to Europe is where UK governments often end up. “The politically astute move is to realise this from the start and find a way to manage a process towards it.”
