NICOLA Sturgeon has hit back at Boris Johnson for appearing to trivialise warnings about a cull of 120,000 pigs because of a shortage of abattoir workers following Brexit.

The First Minister was asked yesterday about the Prime Minister’s remarks, which he made in an interview with the BBC journalist Andrew Marr last Sunday when he suggested it was what normally happened to farmed life stock.

She was asked by SNP backbencher Jim Fairlie at First Minister’s Questions in Holyrood whether she thought “the cull and incineration of pigs that should have gone into our food system” was an unacceptable waste and about the “financial and emotional toll on the farmers involved”.

“It was deeply regrettable that the Prime Minister treated the very serious issues of animal welfare with such disdain on Sunday,” she said.

“The Government is monitoring the specific issue that Jim Fairlie raised very carefully. At the heart of that issue is labour shortages, which are impacting on many sectors of our economy.

“Those labour shortages have been significantly exacerbated by the ending of freedom of movement that came about because of Brexit.”

She added fundamentally “the solutions have to lie” with the UK Government and she called on it to take urgent action.

Asked about warnings of and incineration of up to 120,000 pigs because of labour shortages across the UK, Johnson initially argued that this was no different from what normally happened to livestock.

He said: “I hate to break it to you, Andrew, but I’m afraid our food processing industry does involve killing a lot of animals, that is the reality.

“Your viewers need to understand that. That’s just what happens.”

When Marr pointed out that it would be different, as in this instance the pigs would not be butchered for food and the farmers would receive no income, Johnson said this was part of a wider transformation of the economy post-Brexit.
