Exclusive: Request to postpone Tsai Ing-wen’s trip came before ‘goodwill visit’ to China by David Lammy next week

The UK Foreign Office (FCDO) asked for a visit by the former Taiwanese president to be postponed so as not to anger China ahead of a trip by David Lammy, the Guardian has learned.

Lammy is due to travel to China next week for high-level meetings in his first trip to the country as foreign secretary.
