A ban on banks inserting clauses into client contracts that restrict the future choice of investment banking service providers is among the steps being taken by the Financial Conduct Authority after a 17-month probe into the UK's corporate and investment banking market.

The FCA also plans to tackle banks' manipulation of league table rankings in pitch meetings, and has asked providers of such rankings to review their criteria in an effort to recognise loss-making trades done by some banks "purely to generate a higher position" in the tables and reduce the incentives for banks to conduct such business.
