according to the ever unreliable wiki - "in February 2000 Dyson threatened to shift focus from his Malmesbury plant to a new plant set up in Malaysia because the government would not join the euro."
also "James Dyson mentioned that the market was largest in New Zealand, Australia, Japan and potentially in the Far East market, and therefore the decision to shift production to Far East was driven by the need to get closer to the consumer base. As Dyson was the major manufacturing company in Wiltshire, outside
Swindon, this move created some controversy as trade unionists claimed that the move would impact the local economy hard."
also "In the following year, washing machine production was also moved to Malaysia.The move was driven by production costs in Malaysia which are lower by 30% compared with the UK, however it created a loss of 65 jobs."
