Anyone heard of this before?
UK, Canada and Australia have been very aligned recently on global political issues and it will probably go unnoticed to most but the three issue joint declarations very frequently. (NZ less so because they have taken a far softer stance on China).
For sure we will see even closer relations over the coming years. But it won’t be anything as close as the relationship when we were in the EU.
Distance and time zones will always limit what is possible.
