Rob Warnock is a proud British farmer and the son of a proud British farmer. One day, he hopes to be the father of a proud British farmer, too.

He's also a European Union farmer, but that is not a legacy Warnock wants to pass on to his 6-year-old son.

The 44-year-old plans to vote this week for Britain to leave the EU, even though he knows it will cost his struggling dairy business dear.

Many British farmers feel the same emotional tug. But while their hearts tell them to leave, their heads urge caution. The EU is helping farmers stay afloat at a time when many are struggling.

The benefits of membership in the 28-nation EU may seem intangible to many Britons, who view it as a distant body of Byzantine bureaucracy and obscure regulations.

But farmers know exactly how much they get from the bloc. In Warnock's case it's about 40-thousand pounds (60-thousand US dollars) a year - his share of the subsidy millions of farmers across the continent receive under the EU's Common Agricultural Policy.

"Well I think the EU really holds us back as a nation. Our milk prices, which have been documented, are very low in the UK," he says.

"And I just feel that we can make our own trade deals outside the EU with other countries around the world which I think long term will benefit all the farmers in the country."

He desperately needs things to improve. The price of milk has been plunging for more than two years, hit by what Warnock calls a "perfect storm" of factors, including Russia's ban on EU imports, Chinese stockpiling of powdered milk and production increases in other EU countries.

That is disastrous for Warnock, who tends 450 dairy cows and grows barley and wheat on 650 acres (263 hectares) perched above the English Channel on Britain's south coast.

Warnock's father Jim is not so sure. He intends to vote "remain," worried the subsidies will disappear.

"I know they are saying at the moment if there is a change then we will still get it," he said. "But knowing politicians and knowing the pressure they are going to be under..."

"Leave" campaigners have vowed that the British government will step in to support farmers if the country leaves the EU. The "remain" camp says the pledge is unrealistic: the "leave" side has also promised to boost funding for the health service, maintain defence spending and much more, at a time when the government is committed to cutting public-sector spending.

Farmers have a long list of complaints about the EU, from its complex paperwork to its environmental regulations, which limit which fertilizers and pesticides they can use.

British governments in recent decades have taken a comparatively laissez-faire attitude to agriculture, reluctant to shield domestic producers from international competition.

It's a different story across the Channel in France, where agriculture accounts for a bigger slice of the economy and looms larger in the national consciousness. Militant French farmers regularly stage protests - blocking roads, dumping manure and even herding sheep in the Louvre museum to demand more support from the government.

The National Farmers Union has come out broadly pro-remain, but understands that the community is split.

"Our council met in April, discussed at great length the issues, very good debate, and they came up with the line that basically, on the balance of probabilities as we know it, at the moment farmers are best served to remain within the EU. However individual businesses may differ from that line," says Matt Ware, Head of Government and Parliamentary affairs of the National Farmers Union.

Back on the farm Warnock believes the years of ups and downs have made British farmers resilient. He describes himself as a "passionate dairy farmer" - but worries that if something doesn't change soon, passion may not be enough.

Two decades ago there were more than 35-thousand dairy farmers in Britain.

Today there are only about 10-thousand, and the NFU has estimated that 10 to 20 per cent could go out of business by the end of 2016.

With marching bands and all groups of society out in strength, Norway celebrates Constitution Day, taking pride in its sovereignty.

The small Scandinavian country's independence was hard won, having been ruled by Denmark for more than 400 years, and then by Sweden for nearly another century.

For some people, the experience of having been ruled from afar can explain Norway's reluctance to embrace the European Union project.

"We are on the edge of Europe and we know what it means to be governed from abroad," says Hans Petter Bergseth who is marching with friends from his skiing club. "I think it's deep in our soul that we want to be independent."

But whilst Norway has twice rejected EU membership in referendums in 1972 and 1994, the nation relies on a close relationship with Brussels. Seventy to 80 percent of all Norwegian exports go to the EU markets and cooperation is viewed as essential in the areas of education, research and many more.

Access to the EU's single market comes at a price.

Norway has signed up the European Economic Area (EEA) agreement, and therefore had to implement more than three quarters of all EU laws with no formal influence on how they are drafted.

More importantly, Norway has had to agree to four EU-style freedoms: free movement of goods, services, people and capital.

Today, Norway has more EU migrants per person than Britain. More than 300,000 EU nationals live here, mostly people from Poland and Sweden attracted by the prospects of high-paid jobs and a generous welfare state.

For many companies, this influx of foreign workers has been beneficial. In the small fishing village of Skjervoy several hours north of Tromso, a salmon processing plant has become dependent on foreign workers.

"We don't have enough Norwegian workers who want to work in the fish industry," explains plant manager Tore Pedersen.

Many of these foreign workers are from Romania, like Christian, who arrived nearly four years ago after growing tired of poorly paid jobs in Italy.

"I'm travelling with a Romanian passport, I've had no problem," he explains.

This factory processes 365 tons of fish per day: salmon fillets and whole fish destined for restaurants and dining tables across Europe. It's the main employer in the village, and managers say the business would not be able to grow without foreign workers willing to work the assembly lines.

Here, most workers are unionised and Pedersen says foreign workers are paid the same as Norwegians. Something the unions dispute.

Across the fishing industry, construction industry, hotel and restaurants, they report cases of employers using foreign workers that are not unionized and therefore don't benefit from the collective bargaining agreements that guarantee a minimum wage and regulated working conditions.

"If they don't know the system, they work up to 12 hours," complains union leader Gunn Paulsen, who was picketing a hotel during a four-week long strike across the Norwegian hotel industry calling for better pay. "They ruin it for the next (person) who's coming in, the Norwegians coming in who know the regulations."

Whilst many large hotel groups are unionized, smaller or independent ones without a protection are free to pay their staff whatever they wish. "However low they get in Norway they get higher than in other countries," said Paulsen.

For Professor Bjorn Hersoug from the Arctic University of Tromso, companies that seek to get around ordinary labour conditions by outsourcing the hiring for foreign workers represent a threat to the Norwegian model that balances free markets with a strong social welfare state.

"There is a fear of labour dumping," says Hersoug. "In some instances, it looks like they have working conditions that are considerably worse than agreed through the ordinary agreements for minimum wages for example."

But despite the challenges brought by the EEA agreement, cooperation with the EU and access to the single market remains essential for Norway.

"The EEA agreement is something I would call a corner stone in the Norwegian economy," says Elisabeth Aspaker, the Norwegian Minister of the EEA and EU Affairs.

"We have to face the reality that the EU is our most important market," she says. "We do need cooperation when it comes to research, education, and in many other aspects."

But in another way, we have to face the reality that the EU is our most important market, up to 70 or 80 percent of all the exported goods from Norway go to the EU market, and we do need cooperation when it comes to research, education, and in many other aspects. These days it's about migration, it's about security policy. So the EEA agreement is something I would call a corner stone in the Norwegian economy and if you go to the Parliament today, they will be a solid majority for the agreement although we are not a member of the EU."
