"And yours?"Read the article again. It is not written by the EU but by an economist in Paris.
(Georges Nurdin, MSc., MBA, Ph.D, FinstD, studied international business, management and economics in Oxford (UK), Paris (France), Berlin (Germany) and in the USA. For over 20 years he held global divisional CFO, CEO and Director positions in leading American and European multinational corporations, including GE, Du Pont de Nemours, L&G-Siemens and Valéo. His extensive international experience spans Europe, Russia, the Middle East, Africa, the Americas and Asia.)
For the last ten years Dr Nurdin has advised private and public sector boards and international organisations on international business, economics, trade and cross cultural management.)
If he says the UK negotiated it all very well then I think I would take his word for it, especially with his experience of international business and negotiating.
