The benefits of Brexit are not ecconomic. Brexit came at an ecconomic cost. But to many there are some very important things which were worth the price.
The end of free movement of people. Large numbers of non-British citizens have left the UK.
The ability to determine our own immigration policy.
Complete control over taxation. We can now set variable VAT rates which previously was not possible whilst in the EU.
The UK is no longer subject to rulings from EU courts. If we don't like a law we can just change it.
The ability to set our own trade tariffs. Previously this was controlled at EU level.
Can now sign trade agreements with other countries. Yes we just left the best trade deal we ever had with our biggest trading partner, but now we can sign agreements with other countries if we want.
Blue passports - it may only be symbolic but has become a focus point for many anti-EU campaigners.
Rules relating to pollution are now uder our control. If we want to dump sewerage we can without the EU fining us.
No more UK money going to the EU budget.
For the record I voted to remain and think it was a massive mistake but to many other people the benefits are apparently worth the price.
