The remnants of Greensill Capital, the UK financing company that collapsed earlier this year, filed for bankruptcy in the US, aiming to halt litigation filed by one of its biggest clients, a coal-mining company owned by the governor of West Virginia.

Greensill’s US bankruptcy filing on Wednesday seeks to halt a lawsuit brought earlier this year by coal supplier Bluestone Resources and its owners, West Virginia Governor Jim Justice and his family, according to court papers filed in the US Bankruptcy Court in New York.
