Dr Johan van Zyl, president of Toyota Europe, said:
"Today's announcement that we will manufacture the new Auris at Burnaston, with most engines to be supplied from Deeside, shows our confidence in the skills and capabilities of our Toyota UK members."
However, he added: "As a company, we are doing what we can to secure the competitiveness of our UK operations as a leading manufacturing centre for our European business.
With around 85% of our UK vehicle production exported to European markets, continued free and frictionless trade between the UK and Europe will be vital for future success."
Free and frictionless trade is only possible within a (if not the) Customs Union.
