(Reuters) – The British Prime Ministers national security adviser, Kim Darroch, is expected to propose that ministers have the final decision on deals that affect critical national infrastructure, the Financial Times said, citing sources. The move comes after the parliaments security committee raised concerns about a tie-up between BT Group and Huawei Technologies allowing the Chinese company to become embedded in Britains telecommunications network infrastructure without the knowledge and scrutiny of ministers. In a report, Darroch is expected to recommend tightening the protocols around sensitive infrastructure deals, the paper said, citing two people familiar with the matter.

Huawei, the worlds No. 2 telecoms equipment maker, launched the security centre in 2010 to test its new hardware and software for security risks before being linked to Britains critical infrastructure.
