1 Outside the EU, Britain would be isolated and lose its influence.
Most of the world is outside the EU, including six of the world’s 10 biggest economies. Britain, the ﬁfth biggest, would make that seven.
The BRICS economies (Brazil, Russia, India, China, South Africa) account for 31% of world output and more than half of global economic growth. The EU share of global GDP has fallen continuously from 28% in 1990 to 17% in 2015.  Less than half (48%) of Britain’s external trade is with the EU — even less (46%) if non-EU trade routed through Rotterdam is excluded. 
Britain would retain its membership of the UN Security Council, the OECD, the Council of Europe, the Organisation for Security and Cooperation in Europe (OSCE) and many other international bodies, and regain its own independent seat at the World Trade Organisation.
Britain would be free to negotiate its own foreign, trade and defence policies in partnership with other countries across the world.
2. The EU is a vital source of employment, including three million jobs that depend on exports to Europe as our largest market.
All the EU structural funds spent in Britain (£4.6bn forecast for 2016) are dwarved by our annual net contribution to the EU budget (£15.2bn in 2016).  In other words, Britain outside the EU could spend four times more on these agricultural, social and regional programmes by redeploying this net contribution.
Just under half the stock (48%) of foreign direct investment in Britain is from the EU, unchanged for a decade or more. But while the ﬂow of new investment from the EU has shrunk to 19% (latest 2014), the inﬂow remains constant from US companies (around 55%) and continues to grow from the Far East (22%). 
The share of Britain’s exports going to EU states has dropped steadily from over half (55%) in 2007 to less than half (44%) in 2015.  More jobs in Britain now depend on exports to the rest of the world. Britain’s trade deﬁcit with the EU has trebled, while that with the rest of the world has been cut by two- thirds. Britain’s non-EU exports are growing by 5% a year — while exports to the EU decline. By far the biggest growth markets are China, Switzerland and the Middle East. We don’t need to become part of the USA or China to have trading and other relations with them — why should the EU be diﬀerent?
EU treaties and laws prohibit member state governments from taking measures to save or create jobs which ‘distort’ competition and the free movement of capital, labour and commodities. This includes subsidies, import or capital controls, public procurement contracts favouring local workers or ﬁrms etc. Such restrictions have helped destroy millions of jobs in Britain in steel, coal, manufacturing and agriculture since joining the European Economic Community in 1973.
Outside the EU, Britain could negotiate mutually beneﬁcial agreements with other countries instead of secretive EU pacts that beneﬁt big business, such as the Transatlantic Trade and Investment Pact (TTIP) with the USA.
