Sovereign debt is currently ultra cheap,virtually interest free, to service and it will be for maybe the next decade, and the government, as all governments should also have, have it at a fixed rate so they can borrow very cheaply. .
A few years ago if we had to borrow the same amount as now when rates were high it would have been catastrophic, think Greece a few years ago!
With regard to Brexit its a cancer that isnt going away but it does seem as if both sides are being extremly bullish to save face and the reality probably is its moving faster than either side will publicly admit. as it shows that one or the other side are being "weak" and conceeding .
PersonaIy I still feel angry and that Brexit should never have happened but it has and the best we can hope for is its as painless as possible
