India, May 29 -- Despite easing trade tensions, the U.K. market is turning in a subdued performance on Thursday with investors largely making cautious moves.

The market started off on a positive note as U.S. President Donald Trump's sweeping tariff plans suffered a setback following the US Court of International Trade in Manhattan ruling that the President had overstepped his authority in imposing across-the-board duties on imports from U.S. trade partners.

The court also quashed duties imposed by Trump on Canada, Mexico and China under an emergency-powers law. Meanwhile, China has urged U.S. to "fully cancel the wrongful unilateral tariff measures."

The Trump administration has filed an appeal againt the federal court ruling.
