It's a worry that'll be exercising Tory minds too. Beyond the politically impossible - e.g. withdrawing from the EU - the only long-term solutions to the BJ4BW problem are education reform and welfare reform; giving British workers the skills they need to compete in a global labour market. On paper, at least, a Tory government would put rocket boosters under those reforms. But the effects would still take years to filter into the system proper. In the meantime, it's impossible to imagine that British workers won't lose out to to cheaper, more skilled labour from abroad. And a Prime Minister Cameron may find himself dealing with the political fallout.
