Question to the Department for Business and Trade:

To ask His Majesty's Government how many times the UK has been subject to legal action through investor-state dispute settlement which has been brought either individually or as part of a wider claim; how many times such claims have been successful against the UK; and what was the legal costs of defending those claims.

The UK has investment agreements with Investor-State Dispute Settlement (ISDS) provisions with around 90 trading partners. There has never been a successful ISDS claim brought against the UK, nor has any claim reached arbitral proceedings for the UK to defend.
