Arnold Puech-d’Alissac, vice-president of FNSEA, predicted the European Union’s farmers could lose billions in the Common Agricultural Policy budget when the UK leaves the bloc.
However, he hinted if the UK were to withdraw budget contributions to Brussels its financial industry would face being exiled from the European markets.
Speaking to France 24, Mr Puech-d’Alissac was asked about the impact of Britain’s European divorce, he said: “We can lose some billions, but if you lose some billions out the EU budget the UK will lose all the European markets for its financial services, for example.
“That will be a big problem for the UK, the negotiations just started, we’ve got 18 months for an agreement – they will find an agreement.”
The Frenchman also voiced concerns over the potential of a hard border being introduced between the Republic and Northern Ireland.
Mr Puech-d’Alissac suggested “strict controls” would have to be introduced on the potential border to ensure EU standards are upheld with the prospect of the UK importing more of its food from outside the bloc.
Brexiteer, technology entrepreneur and Britain’s biggest farmer, Sir James Dyson, however, hinted it is “not big deal” for country’s farming industry if a deal is not struck with the EU over agriculture.
He also called on the Government to ensure farmers are not shunned when post-Brexit trade deals are made across the globe.
Sir James told The Spectator insisted it was important for the Government would have to continue farming financial subsidies after the UK leaves the EU.
He said British farmers will be at a “disadvantage” to their European counterparts because they will be continued to be subsidised by the EU.
Sir James concluded British farms would go bust if an influx of cheap chlorine-washed chicken, acid-washed pork and hormone-injected beef was introduced from the US, adding: “Cattle farmers would just have to give up.”
National Farmers Union vice-president Guy Smith also agreed Government assistance helped British agriculture stay competitive globally.
He told BBC News: “What we are rightly weary of is having to compete against farmers in other parts of the world who get greater levels of support, or who have different costs of production because of different policy.”
A spokesman for the Department for Environment, Food and Rural Affairs said Environment Secretary Michael Gove remains committed to the long-term support of Britain’s farmers.
