Britain and Europe are not 'opposition' but 'partners' in the Brexit negotiation. In the negotiating rooms, both sides will be working together to provide as much value to their partners as they can, to keep the relationship on a healthy footing, and find ways of 'expanding the pie'.

This is the main model of negotiation in operation in Western countries these days, and, unless the relationship collapses, that's what we should expect of our government officials in the next year (or few years) of talks - unless things go badly wrong.

Both sides of this negotiation will do their research and will brainstorm interesting and engaging ways to give their partners things they value highly, but which cost little to concede.

So, if you want to give yourself and your industry an outsized chance of getting what you want from the negotiations; get your requirements out there - on social media, in the newspapers - just make sure both your own government and their negotiating partners are aware of it. Work with your industry body if you need to.

Those industries that make a clear and compelling case in the public arena will help shape the political agenda and the ideas in the minds of the people at the table. 

Now the Brexit process is finally through that second tortuous milestone, it's time to get down to business and help the professional negotiators do the best possible job for you.
