A cross-party committee said helium had not fixed them the "full facts" 2 years agone erstwhile they were considering his suitability for the BBC role.
He should see however this affected spot successful him and the BBC, it said.
Mr Sharp apologised if MPs had not had each the details they needed.
His engagement successful the then-Prime Minister Mr Johnson obtaining an £800,000 indebtedness warrant has travel nether scrutiny since the Sunday Times archetypal reported the claims past month.
Businessman Sam Blyth, a distant relative of Mr Johnson and Mr Sharp's friend, had reportedly raised the thought of acting arsenic a indebtedness guarantor for Mr Johnson successful 2020.
When helium appeared earlier MPs connected the Commons Digital, Culture, Media and Sport (DCMS) Committee this week, Mr Sharp said helium did not assistance put this warrant oregon springiness Mr Johnson fiscal advice.
He was named arsenic the government's preferred campaigner for the BBC occupation successful January 2021 and astatine the clip the DCMS Committee backed his appointment. The government's prime is yet decided by the premier minister, connected the proposal of the civilization secretary, who is successful crook advised by a panel.
In its study published connected Sunday, the DCMS Committee is highly captious of Mr Sharp's nonaccomplishment to notation immoderate engagement helium had successful events surrounding the indebtedness erstwhile they were considering his suitability for the job.
The study said his decisions to "become progressive successful the facilitation of a indebtedness to the then-prime curate portion astatine the aforesaid clip applying for a occupation that was successful that aforesaid person's gift" and nonaccomplishment to disclose this to the committee undermined assurance successful the nationalist appointments process.
Earlier this week Mr Sharp had told the committee he had met Cabinet Secretary Simon Case successful December 2020 to get support to walk connected Mr Blyth's details to him.
However, astatine the aforesaid gathering helium had told Mr Case that helium had applied for the BBC job, and truthful agreed helium would person "no further participation" successful bid to debar immoderate struggle of involvement oregon cognition of struggle fixed his exertion to the BBC.
In is highly captious report, MPs said Mr Sharp had recognised the request to beryllium "open and transparent" by bringing it to the attraction of the furniture secretary, but "failed to use the aforesaid standards of openness and candour successful his determination not to divulge this accusation during the interrogation process oregon to this committee during the pre-appointment hearing".
"Mr Sharp's nonaccomplishment to disclose his actions to the sheet and the committee, though helium believed this to beryllium wholly proper, represent a breach of the standards expected of individuals applying for specified nationalist appointments," the study added.
The study concluded: "Mr Sharp should see the interaction his omissions volition person connected spot successful him, the BBC and the nationalist appointments process."
A spokesperson for Mr Sharp said helium did not facilitate an instauration betwixt Mr Johnson and Mr Blyth and helium was not progressive successful the statement of a indebtedness betwixt them.
"Mr Sharp appreciates that determination was accusation that the committee felt that it should person been made alert of successful his pre-appointment hearing. He regrets this and apologises.
"It was successful seeking astatine the clip to guarantee that the rules were followed, and successful the content that this had been achieved, that Mr Sharp acted successful bully religion successful the mode helium did."
The spokesperson added: "Mr Sharp believed helium had dealt with the contented by proactively briefing the furniture caput that helium was applying for the relation of BBC chair, and truthful beyond connecting Mr Blyth with Mr Case, helium recused himself from the matter."
The DCMS Committee study was besides captious of ministers who had defended the determination to endorse Mr Sharp successful 2021 aft the enactment implicit the indebtedness broke, contempt the information they had not been told astir the situation.
"The information that ministers person cited this committee's archetypal study connected Mr Sharp's assignment arsenic a defence of the process was followed, erstwhile we were not successful afloat possession of each the facts that we should person had earlier america successful bid to travel to our judgement, is highly unsatisfactory," the study said.
Prime Minister Rishi Sunak said Mr Sharp was made arsenic BBC president pursuing 2 "transparent and rigorous" assignment processes, adding the assignment was made by his predecessor.
According to the Sunday Times, a leaked memo from Mr Case allegedly warned Mr Johnson to "no longer" inquire for fiscal proposal from Mr Sharp.
But the MPs successful this caller study said determination was an "unresolved issue" arsenic to wherefore the furniture caput had believed Mr Sharp had been giving fiscal proposal to Mr Johnson and called connected the Cabinet Office to "clear up the confusion" fixed that Mr Sharp had said this was not the case.
Acting Chair of the DCMS Committee Damian Green MP said: "The nationalist appointments process tin lone enactment efficaciously if everyone is unfastened and transparent, yet Richard Sharp chose not to archer either the assignment sheet oregon our committee astir his engagement successful the facilitation of a indebtedness to Boris Johnson."
For those of america pursuing this communicative successful detail, a fascinating constituent is the memo written by the Cabinet Office to Boris Johnson connected 22 December 2020.
Mr Sharp is astir to beryllium announced arsenic BBC chairman, a relation appointed by the then-prime minister. So Boris Johnson is told helium indispensable "no longer inquire him proposal astir your idiosyncratic fiscal matters".
Mr Sharp says helium ne'er gave Mr Johnson proposal astir his finances. So wherefore is the memo phrased successful that way? The committee has called upon the Cabinet Office to wide up the disorder immediately.
The committee doesn't telephone for him to resign, but it does travel adjacent to suggesting Mr Sharp considers his presumption erstwhile it says helium should see the interaction his actions person had connected spot successful him and the BBC.
It is not astatine each definite that, adjacent if helium had declared this imaginable struggle of interest, idiosyncratic other would person been chosen arsenic BBC chairman.
The process, though, is nether scrutiny and we present await the probe by the nationalist appointments watchdog.
Shadow civilization caput Lucy Powell said the BBC chairman's presumption was becoming "increasingly untenable" and it "throws into superior uncertainty the impartiality and independency that is truthful cardinal to spot successful the BBC."
The Liberal Democrats said Mr Johnson besides needed to reply questions arsenic portion of an autarkic inquiry.
The watchdog that oversees however nationalist appointments are made is besides reviewing the process of however Mr Sharp was hired.
William Shawcross, the Commissioner for Public Appointments, recused himself from heading up that reappraisal past month aft penning to the DCMS to accidental helium had met Mr Sharp connected "previous occasions".
The BBC is besides conducting its ain interior reappraisal implicit immoderate imaginable conflicts of involvement Mr Sharp whitethorn person successful his relation arsenic BBC chairman.
