Suwit's mission will be similar to that of Lord Jones, Britain's minister of trade and investment, and executives from 10 top UK firms during their trip here last March.

According to the Board of Investment, British investors submitted 18 applications with a combined investment of Bt4.249 billion in the first half, up from 13 applications worth Bt1.14 billion in the same period last year.

They include SME manufacturers such as Triumph Motorcycles, plus Boots, Tesco and Standard Chartered.
