A little problem with Brown’s Maginot Line?

Mark Devenport throws up a question that should be of interest both to Gordon Brown and to his Tory party opponents. If Britain is to have a new Border Guard force, where exactly is the border?Our north/south border is virtually non existent, as is the east west. This would leave Brown with something like an Maginot Line , in which Britain’s coast, ports and airports are heavily defended, whilst leaving the Republic’s lighter security and tiny navy to guard it’s ‘western approaches’ against drug traders, terrorism, and human trafficking.
