I think Tamora is talking lots of sense by saying staying in the EU has far greater risks. It is a shrinking market, compared to the rest of the world, and yet ties it's members to it so we aren't allowed to make our own trade deals (if we leave, we would regain our seat on the WTO). Within a decade, think what other countries could be part of it; including Turkey which effectively brings our border to Syria and Iraq.
The most credible argument of the Remain campaigners is that leaving would create uncertainty: they may be right about that but it will be short lived, and afterwards we can govern ourselves and be prosperous. There would be a period of negotiation with the EU for 2 years before we actually leave, and no other sovereign country in the world has said they would not make trade deals with us.
Please, Vote leave.
