By 'implementing it', I mean you can't just say that's it. We've left we're done. Leaving is the 'easy' part. Implementing leave is the hard part and what determines its success or not. And as the economy and country is in a right state after COVID and Truss, we aren't starting from a great place I'll give you that.
Implementing means, over the next 10 years we need to start negotiating, forging new links, setting out new pathways, striking new deals, getting better connected on the world stage and finding ways to re-connect and repair relations with Europe which bring life, in a different (maybe even better) way, back to our partnerships and collaborations in research and other areas. Implementation is lengthy, and hard, and requires a strong, committed, unified, forward thinking government that can restore the markets faith in Britain, and the people's faith in Brexit. Sadly we don't have that at present, but ever the optimist...
Ultimately, we need the politicians to believe in brexit. You can't win the Olympics if you don't believe you can. What's even the point in trying. You can't make a successful Brexit if you don't think you can. It's defeatest and dooms us to failure. We need a government that believes and makes it happen.
With change comes opportunity. We need to see those areas which are not working and make them work for us. Admittedly, being out of Europe is a huge huge shift. A massive change and there has been real economic and personal consequences for people. But we can not only recover, but forge something very very good at the end of it if we try. If we make sure we connect more globally with partners. If we see ourself as a more global player. If we take the lead on new partnerships, rather than just sit morning the loss of old ones.
Anyway.. that's my view :)
