Tariff barriers are only allowed in world trade in emergency situations.

Britain has the largest current account deficit in the world as a percentage of GDP. That sounds like an emergency situation to me. Part of the problem is paying the interest charges on the national debt.

The interest payments on the national debt amount to £1bn a week.

The only way to turn this situation around is to expand Britain’s manufacturing output.

None of the three major parties have any policies that will help and support the expansion of British manufacturing industry.
