ASI Madsen Pirie writes The Times's Thunderer column on how EU subsidies of rapeseed add to the nation's hayfever:
By careful breeding, Canadian scientists produced a low acid version. Rapeseed was transformed, and spread rapidly across Britain, changing the look of the spring landscape with its lurid yellow flowers. Its UK production soared from about 1,000 tonnes in 1970 to more than two million tonnes in just a few years.
It was not the crop itself that made it a farmers’ favourite but the EU subsidy paid to those who planted it. The EU paid cash not for the crop that resulted but to fund the seeds and planting. It was a bonanza for landowners.
