(Reuters) - Britain's competition regulator said on Tuesday it was considering whether asset management firm BlackRock (NYSE: BLK )'s 2.55 billion pound ($3.23 billion) acquisition of UK data firm Preqin would raise competition concerns in the local market.

The Competition and Markets Authority, which has not yet launched its formal probe into the deal announced in June, has invited interested parties to submit their views on the impact the deal could have on competition in the UK.
