Britains johnson condemns crazy brexit customs plan

I think there may be some confusion here!

Boris Johnson is a British politician who has been the Prime Minister of the United Kingdom since July 2019. However, I'm not aware of any instance where he has condemned a "crazy Brexit customs plan" because, well, he's the one who has been leading the UK's Brexit negotiations!

It's possible that you may be thinking of a different politician or a specific proposal that was put forward during the Brexit negotiations. Could you provide more context or clarify what you mean by "crazy Brexit customs plan"? I'd be happy to help you understand the situation better!
