Well Brutus helped to murder Caesar, was driven out of Rome branded a murderer, got enmeshed in the ensuing civil war and was defeated in battle alongside his co-conspirator Cassius and killed himself, all within three years of his grabbing of that flood tide in search of fortune that your quote referred to. A good quote all right (it was the play I did for my Eng Lit 'O' Level), but it all led to the sort of outcome we can cheerfully expect from brexit. Disaster, in other words. Happy to finish the tale for you, Nigel.
