EU benefits are about more than business – Greens welcome referendum | Letter from Natalie Bennett, Caroline Lucas and others

The last few days have seen a tussle between big businesses over whether or not Britain should stay in the EU. But a focus solely on corporate interests undermines the issues at the heart of this debate.

The EU is more than just a market. Indeed, with the rise of multinational corporations increasingly capturing our national politics, EU protections for workers' rights give us some comfort in the face of cuts to so-called red tape. The EU has also brought in a cap on bankers' bonuses and a tax on City speculation. With the Tories determined to water down these EU rules, it's vital we fight to maintain them.
