Ms Adams told MPs she hadn't seen the details of pay-offs to Mark Byford and Sharon Baylay, but now says she helped draft plans as Martk Thompson goes to war with BBC Trust. Ms Adams, who quits the corporation of coming month, had told the Commons Public Accounts Committee hearing she didn't see a note outlining plans for pay-offs to deputy director general Mark Byford and marketing boss Sharon Baylay. Lucy Adams admits she was involved in drafting key memo to trust that she claimed in previous evidence not to have seen Lucy Adams, the BBC's HR director, has written to MPs to correct her evidence to parliament about her involvement in agreeing the severance payment for a former senior executive. Adams admitted in fresh evidence released by the commons public accounts committee that she was involved in drafting a key memo to the BBC Trust that detailed a controversial severance payment to Mark Byford, the former deputy director general. Mark Thompson, the former director general, described adams in evidence. Thompson added his evidence to the PAC: This is not just a memo for information, from me to the BBC Trust. Trust officials were themselves engaged closely in its composition and would not let it be formally submitted to the chairman until the wording was perfect from their point of view." It was responsible for approving significant payoffs, in what promises to be a combative hearing. I think this does raise a deeper and more fundamental problem, which some of us have been banging of the BBC and the fact you have this organisation, the trust, which doesn't really act as an effective regulator nor as an effective cheerleader because it's expected to do both jobs in one, he told BBC Radio 4's The World at One on Friday.
