A report into how UK Athletics handled decisions about its relationship with disgraced running coach Alberto Salazar found the board changed its stance on severing ties with him.
This came after some members of the board claimed they felt subjected to "in effect blackmail" by UKA's performance team, who suggested their jobs would become untenable were British four-time Olympic champion Mo Farah to be forced to split from his coach.
A 130-page independent report published on Friday found UKA took "reasonable" decisions given the circumstances but its handling of the scandal "could have been better".
Salazar was banned from the sport for four years in October after being found guilty of doping violations following an investigation by the US Anti-Doping Agency (Usada) and a two-year court battle.
The American ran the Nike Oregon Project (NOP) which was home to Farah between 2011 and 2017.
There is no suggestion of any wrongdoing by Farah, who has never been accused of breaking anti-doping rules.
In light of the claims against Salazar in a 2015 BBC Panorama episode, an internal performance oversight committee (POC) was set up, which concluded there was "no concern" about letting Farah continue to be coached by Salazar.

In November, UKA commissioned the independent review into the scandal, led by sports law barrister John Mehrzad.
In the report, Mehrzad makes a series of recommendations related to future reviews, strengthening the coaching code of conduct and governance of "high-risk" situations, all of which have been accepted by UKA.
The report describes how, after the POC's findings, the UKA board decided unanimously that it would suspend its consultancy arrangement with Salazar.
It also says that "the board recommended that Farah leave Salazar". When told of the board's position, the senior UKA performance team "strongly expressed" their view that Salazar should remain coaching Farah.
Mehrzad noted that the performance team was "concerned that Farah leaving Salazar/the NOP would negatively impact on UKA performance (and related UK Sport funding) aims: medal-targets for the World Athletics Championships later in 2015 and, more particularly, at the Rio Olympics the following year in 2016".
Following these concerns, and given UKA did not have the contractual power to force Farah to leave Salazar, the board "ultimately accepted unanimously that Farah would continue to be coached by Salazar".
The report finds Salazar was only verbally informed of his consultancy agreement being terminated. This was not put in writing, and an "administrative oversight" meant he was sent a renewal contract in 2016. Mehrzad concludes this "could have been better".
The report also says the UKA board described the position taken by performance director Neil Black and coach Barry Fudge on the issue as "in effect blackmail", after the pair said their roles would be "untenable" if the Salazar-Farah coaching set-up was severed.
The suggestion of blackmail is strongly denied by Black and Fudge, who told Mehrzad that their role would have been "fundamentally undermined" if Farah had been forced to split from Salazar. BBC Sport has approached Black and Fudge for comment.
The board accepted that Farah would continue to be coached by Salazar, and the report says that "in practical reality little changed".
The report says that, while the board's decisions "were within the reasonable ambit open to it in terms of decision-making at the time… the implementation process... could have been better".
UKA responded to the report by saying: "The review... has found that the decisions made by UKA in response to a BBC Panorama in 2015... were reasonable at those times, taking into account the then circumstances and the information then available.
"The report also finds that the follow-up to those decisions could have been better managed and implemented."
Nic Coward, UKA's chair, acknowledged that the organisation needs to "lead by example".
The report reveals that no minutes were taken of a special board meeting on 27 July 2015, when the initial findings of the internal review were presented to the UKA board.
One of the five recommendations of the report relates to accurate minute-taking.
What's the background to the case?
Salazar was appointed as a consultant to UKA's endurance programme in 2013 after he masterminded Farah's 5,000m and 10,000m gold medals at the London 2012 Olympics.
Salazar's eventual ban by Usada triggered criticism of senior officials.
Black, who described Salazar as "a genius" during their time working together, left his position shortly after the Usada finding.
Fudge, who was the contact point between Salazar and UKA, has continued in his role and will help prepare the Great Britain team for the 2020 Tokyo Olympics.
The report gives detail on the roles played by the pair in June 2015 in response to the allegations in Panorama.
It reads: "So strongly did Black and Fudge feel about the issue, that they indicated that their positions would be 'untenable' if there was a knee-jerk severing of the relationship with Salazar by the board.
"Having then been informed of that position, some on the then UKA board felt that the stance taken by those individuals was 'in effect blackmail'.
"However, those performance figures deny that to have been the case. Rather, they believed their position to be very straightforward: their ability to deliver against medal-targets set by UK Sport would be hampered if Farah was forced against his will to split from Salazar.
"If that was the decision taken by the board, they felt the central performance goals of their own respective roles and responsibilities would be fundamentally undermined."
Mehrzad also found that the language used in UKA's public statements about its decisions regarding Salazar in 2015 "could have been reasonably perceived as definitive at times".
In hindsight, some UKA board members from 2015 "suggest that more careful language should have been used, especially when Usada's investigations were ongoing and its outcome unknown".
Details of 2015 review published
The executive summary of UKA's 2015 review was also published for the first time on Friday.
The objectives of the review, which had previously not been disclosed, were to "establish whether our organisation's confidence in the Oregon Project is well founded in regard to Mo Farah's training programme", "to establish whether our organisation's confidence in the Oregon Project is well founded in regard to UKA's overall endurance programme" and "to consider any lessons learned as a result of this specific review for UKA's overall performance programme".
In the recommendations presented to the UKA board on 27 July 2015, the performance oversight committee found that "despite the POC not finding any evidence to cause concern specifically around MF [Mo Farah] or the wider UKA endurance programme and the links with the OP [Oregon Project]; the UK Athletics board needs to consider the potential reputational damage linked to the claims currently known to have been made about Alberto Salazar".
There were also "concerns and frustrations" raised to the POC that "our endurance programme is 'all things MF' and that there is limited development outside that".
In light of this, UKA agreed to review staffing roles to ensure "the support provided by UKA to MF does not detract from the wider strategical and operational management and development of the UKA performance programme (Olympic and Paralympic) and endurance programme".
On UKA's 2015 internal review, Mehrzad said that, while "there is no basis to question the impartiality of the POC, which carried out the internal review, UKA is recommended to consider appointing an external, specialist independent person or body to carry out or chair a review into serious allegations (whether doping-related or otherwise) in the future".
He added: "By doing so, there can be no rational perception of a lack of independence. Such an approach to reviews has also been the direction of travel within funded sport since around 2016.
"It is, of course, noted that UKA has commissioned this independent review - which is in line with this recommendation. However, it is likely that the sea of speculation concerning its 2015 and 2017 decisions may have been calmed much earlier had an independent review been commissioned in the first place."
Coward said: "John Mehrzad QC has delivered a thorough and detailed independent review into the decisions taken by the UKA board in 2015 and 2017, how they were taken, and the follow-up.
"The depth of insight provided by this independent review is timely support for a number of changes that need to happen, and which we are already getting on with. The sport has to meet the highest possible standards, and we need to lead by example."
