'The European Union is the most successful regional trade bloc in the world,

but its greatest success, its Single Market, could not have been achieved

without the willingness of its member states to share their powers on key

issues'.

Using the European Union as the basis for comparative analysis, select

another regional trade bloc, and critically evaluate the level of

integration it has achieved. You should also highlight any barriers to

securing the level of integration required to search for a single market like

the European Union's.
