Question to the Department for Business and Trade:

To ask the Secretary of State for Business and Trade, what estimate she has made of the cost to the public purse of successful investor state dispute claims against the UK under the terms of the Energy Charter Treaty.

The UK has investment agreements with ISDS provisions with over 90 trading partners, including within the Energy Charter Treaty (ECT). There has never been a successful ISDS claim brought against the UK, nor has the threat of potential claims affected the Government’s legislative programme.
