Brexit has led to a shortage of truck drivers in the UK, resulting in milk being poured into sewers due to a lack of transportation. Farmers are under pressure to find new suppliers and solutions, with some delivering milk directly to consumers to avoid waste. The situation is causing concern for the farmers' union and the British government, with the industry expected to provide most of the solutions. Progress is being made in testing and recruiting new staff, with expectations of wage increases and improved working conditions.
