1. Various of abandoned coal mine

2. SOUNDBITE (English) Eddie Cullen, excavator driver:

"At first, everybody was frightened when the pit (coal mine) shut, but life has got to go on and we've still done well. There has been a lot of unemployment in Wales, but we've just got to travel further for the work, like me."

3. Cutaway of dog

4. SOUNDBITE (English) Eddie Cullen, excavator driver:

"Everybody has just had enough, you know. They want their identity back as a country, you know, rather than being run by people from outside the country."

5. Grafiti on abandoned coal mine reading (English) "Don't steal our heritage."

6. Various of abandoned coal mine

10. Various of new college partially financed by the EU

11. Various of new recreational centre partially financed by the EU

12. SOUNDBITE (English) Paul Thomas, occupational therapist:

"My dad worked at the steelworks. He used to come home and tell us when we were kids that he'd have to use a push bike to go from one end of the factory to the other end of the factory. Sadly it's gone now, but with the EU funding we've got the leisure centre now, we've got the college, we've got the school, we've got the hospital. There was going to be more development here, but we don't know what's going to happen now."

Near Brynmawr - 30 June 2016

13. Various of the town

14. Street in centre of town with sign reading (English) "Vote Leave."

15. Close of Welsh flag

16. SOUNDBITE (English) John Thompson, retired truck driver:

"I would say no. We haven't seen no benefit to this area at all. They do leave us a road now as you know, you've seen the sign, the European sign on it, but what you've got to think about is: they don't give us nothing. It's our money, part of our money coming back to us. We've given them the money and they just send some back to us. They don't give us nothing really."

Cardiff - 29 June 2016

17. View over Cardiff Bay with National Theatre Wales in foreground

18. Close of sign reading (English and Welsh) "National Assembly for Wales."

19. SOUNDBITE (English) Andrew RT Davies, Welsh Conservative leader:

"Well, it's British money in the first place. It goes out there, and we leave 50 percent of that money out there and 50 percent comes back. So that's the narrative here. We are all for embracing cooperation with other countries, we are all for working as allies in national security and self-defence, but there comes a point where self-determination has to come into this as well."

20. Various of Andrew RT Davies, Welsh Conservative leader

21. SOUNDBITE (English) Andrew RT Davies, Welsh Conservative leader:

"Very often, these schemes will seem to be managed by elites and ultimately not delivering for the communities that were supposed to benefit, and so people actually used the opportunity of the referendum to say 'whoa, stop the car, I want to get out, the way this car is driven, we're going to hit a brick wall."

Pontypridd - 29 June 2016

22. Various of Jenny Hughes, co-founder of Pontydysgu, a Welsh educational research institute, looking at the company website

23. SOUNDBITE (English) Jenny Hughes, co-founder of Pontydysgu:

"So, all of a sudden, we personally can't tender for anymore, but more particularly, our partners or consortia that we work with are saying now, 'well, actually we don't want to work with you' - they do want to work with us but they don't feel they can because they don't know what's going to happen."

Cardiff - 29 June 2016

25. Various of Ed Poole, lecturer in Politics and International Relations at Cardiff University, at his desk

26. SOUNDBITE (English) Ed Poole, lecturer in Politics and International Relations at Cardiff University:

"I would say that unfortunately, in the long term, Wales might have shot itself in the foot on an economic basis."

27. Cutaway

28. SOUNDBITE (English) Ed Poole, lecturer in Politics and International Relations at Cardiff University:

"It's not just the structural funds that benefit the poorest areas in Wales - that's to the tune of about 400 million (British) pounds (534 million US dollars) per year. It's also the agricultural policy, which is very specifically supporting small scale businesses, which is Wales' specialism because of the topography of Wales. It's about 260 million (pounds, 347 million US dollars) per year, and it's also access to the single market."

Merthyr Tydfil - 30 June 2016

29. Various of open-pit mine and surrounding landscape

It's been 25 years since the Penallta Colliery fell silent: the river once black with soot is now green and nature has taken back its place in this valley in South Wales.

Eddie Cullen grew-up here in a family of miners and remembers the decline of the town and the sorrow at seeing the heart of his community torn away.

"Everyone was frightened when the pit shut," he says.

With dire poverty and high unemployment rates, South Wales has benefited from generous grants and financing schemes from the European Union to rejuvenate the area's economy.

Yet on 23 June - the day of the UK referendum - the region voted massively to leave the EU.

The modern highway connecting Brynmawr with other former coal-mining towns in the Valleys region of South Wales was partly funded by the European Union, replacing a three-lane road known for its many deadly accidents.

In Abbw Vale, where 62 percent voted out, EU funds have also been used to improve railway lines, open museums, schools and training centres built where the steel works once stood.

Paul Thomas, who voted 'remain', worries Brexit could jeopardise these achievements.

"There was going to be more development but we don't know what's going to happen now," he says.

But back in the old city centre retired truck driver John Thompson doesn't agree, saying that "there's been no benefit to this area at all"

"Leave" campaigners say many of the EU projects are gimmicky and haven't led to any tangible improvements for people.

Also, they consider the EU money as British money to begin with, since overall Britain contributes more money than it gets back from the EU.

Welsh Conservative leader Andrew RT Davies, was one politician to go against the party's UK leader, Prime Minister David Cameron, and vote for Britain to quit the EU

Davies used the metaphor of an out-of-control car to describe the EU, saying that people used the referendum to effectively say "I want to get out, the way this car is driven, we're going to hit a brick wall."

But for one Welsh company, Brexit was the brick wall.

In Pontypridd, a town climbing up misty hillsides north of Cardiff, Jenny Hughes said her education consultancy firm lost three potential contracts the day after the referendum as European partners pulled out.

Even though Wales receives hundreds of millions of pounds annually in EU funding, more than half of the Welsh electorate voted for Britain to leave the EU.

Puzzling many analysts, the "leave" vote was strongest in deprived post-industrial areas that have arguably benefited the most from EU support.

"Wales might have shot itself in the foot," says Ed Poole, lecturer in politics at Cardiff University, explaining that Wales has been one of the biggest net beneficiaries of being in the European Union.

A study he co-authored before the vote estimated that Wales receives a net annual benefit of 245 million (British) pounds (327 million US dollars) from the EU budget, or about 79 pounds (105 US dollars) per head.

That compares with a net contribution of 151 pounds (201 US dollars) per head for all of the United Kingdom.

It's possible, Poole says, that some voters didn't fully understand the role of EU funds in supporting their communities - or chose to ignore it.
