Wales goes to the polls this Thursday to decide if Britain should leave or remain in the European Union.
It's sure to be a close run vote with the 'Leave' and 'Remain' camps hoping to secure those undecided voters in the final stages of their campaigns.
But has south west Wales seen any financial benefit from Brussels? Many argue that the money has huge advantages for Wales as a whole - while others say that funding is money sent back to Wales from Brussels.
Here are some examples of how EU funds have been spent in the area:
