The centre-left and left of British politics has been pretty united on the Europe Union over the last few decades. That is because the principle of European unity and co-operation fits so strongly with our internationalist principles – solidarity, standing together, and the collective being stronger than the individual.
It is why being in Europe has always worked so well for Britain. From the good, unionised manufacturing jobs that depend on our exports to Europe, to the maternity leave and paid holiday enshrined in EU law, to the lower prices created by the single market, British people are better off in Europe. And co-operating with our partners on carbon emissions, anti-terrorism and the European Arrest Warrant helps keep our streets and our environment safer.
