The Financial Conduct Authority (FCA) has been investigating the matter this year, according to the report https://www.bloomberg.com/news/articles/2018-08-17/goldman-is-said-to-face-u-k-probe-over-mifid-reporting-faults.

Earlier this year, a former Goldman Sachs employee sent a complaint to the FCA alleging that the bank's approach was to flood regulators with too much data and inaccurate information in breach of compliance guidelines, the report said.

The EU's Markets in Financial Instruments Directive II, dubbed MiFID II, which took effect earlier this year, states investment research must be priced separately from other broker services to ensure transparency and better value for money.

Goldman Sachs did not immediately respond to Reuters request for comment, while the FCA could not be reached outside business hours.
