=== Conflict of interest ===
Public understanding of the claims sharply changed in February 2004 with revelations by The Sunday Times of an undisclosed conflict of interest on Wakefield's part in that, two years before the paper's publication, he had been approached by Richard Barr, a lawyer of Justice, Awareness and Basic Support, who was looking for an expert witness to start a planned class action regarding alleged "vaccine damage". Barr hired Wakefield at £150 per hour, plus expenses, and only then did they recruit the twelve children, actively seeking the parents of cases that might imply a connection between MMR and autism. Barr and Wakefield convinced the UK  Legal Aid Board, a UK government organization to give financial support to people who could not afford access to justice, to assign £55,000 to fund the initial stage of the research. According to journalist Brian Deer, the project was intended to create evidence for the court case, but this only became publicly known six years after the Lancet report, with the newspaper's first disclosures.
Based on Deer's evidence, the Lancet's editor-in-chief Richard Horton said Wakefield's paper should have never been published because its findings were "entirely flawed". Although Wakefield maintained that the legal aid funding was for a separate, unpublished study (a position later rejected by a panel of the UK General Medical Council), the editors of The Lancet judged that the funding source should have been disclosed to them. Horton wrote, "It seems obvious now that had we appreciated the full context in which the work reported in the 1998 Lancet paper by Wakefield and colleagues was done, publication would not have taken place in the way that it did." Several of Wakefield's co-researchers also strongly criticized the lack of disclosure.

=== No ethical approval ===
Among Deer's earliest reported allegations was that, contrary to a statement in the paper, Wakefield's research on the 12 children was conducted without any institutional review board authorization—a claim quickly denied in February 2004 by both the paper's authors and the Lancet. The paper itself said, "Ethical approval and consent. Investigations were approved by the Ethical Practices Committee of the Royal Free Hospital NHS Trust, and parents gave informed consent." The dispute over this would remain unresolved, however, until settled in the English High Court in March 2012, where a senior judge vindicated Deer. Quoting the text, Justice Mitting ruled, "This statement was untrue and should not have been included in the paper."

=== Retraction of an interpretation ===
The Lancet and many other medical journals require papers to include the authors' conclusions about their research, known as the "interpretation". The summary of the 1998 Lancet paper ended as follows:

Interpretation We identified associated gastrointestinal disease and developmental regression in a group of previously normal children, which was generally associated in time with possible environmental triggers.

In March 2004, immediately following the news of the conflict of interest allegations, ten of Wakefield's 12 coauthors retracted this interpretation, while insisting that the possibility of a distinctive gastrointestinal condition in children with autism merited further investigation. However, a separate study of children with gastrointestinal disturbances found no difference between those with autism spectrum disorders and those without, with respect to the presence of measles virus RNA in the bowel; it also found that gastrointestinal symptoms and the onset of autism were unrelated in time to the administration of MMR vaccine.
Later in 2004, the newspaper's investigation also found that Wakefield had a further conflict of interest in the form of a patent for a single measles vaccine, had manipulated evidence, and had broken other ethical codes. The Lancet paper was partially retracted in 2004 and fully retracted in 2010, when Lancet's editor-in-chief Richard Horton described it as "utterly false" and said that the journal had been deceived. Wakefield was found guilty by the General Medical Council of serious professional misconduct in May 2010 and was struck off the Medical Register, meaning he could no longer practise as a doctor in the UK. In 2011, Deer provided further information on Wakefield's improper research practices to the British Medical Journal, which in a signed editorial described the original paper as fraudulent.
Deer continued his reporting in a Channel 4 Dispatches television documentary, MMR: What They Didn't Tell You, broadcast on 18 November 2004. This documentary reported that Wakefield had applied for patents on a single measles vaccine that claimed to be a potential rival of MMR, and that he knew of test results from his own laboratory at the Royal Free Hospital that contradicted his own claims. Wakefield's patent application was also noted in Paul Offit's 2008 book, Autism's False Prophets.
In January 2005, Wakefield sued Channel 4, 20/20 Productions, and the investigative reporter Brian Deer, who presented the Dispatches programme. However, after two years of litigation, and the revelation of more than £400,000 in undisclosed payments by lawyers to Wakefield, he discontinued his action and paid all the defendants' costs.
In 2006, Deer reported in The Sunday Times that Wakefield had been paid £435,643, plus expenses, by British trial lawyers attempting to prove that the vaccine was dangerous, with the undisclosed payments beginning two years before the Lancet paper's publication. This funding came from the UK legal aid fund, a fund intended to provide legal services to the poor.

=== Support for Wakefield ===
Despite The Sunday Times disclosures, Wakefield continued to find support. Melanie Phillips, an influential columnist with the Daily Mail, called the reporting of Wakefield's contract with the solicitor Richard Barr "a smear whose timing should raise a few eyebrows."
According to Deer writing in the BMJ, the General Medical Council hearing was also criticized by Richard Horton, the Lancet editor: "My own view is that the GMC is no place to continue this debate. But the process has started and it will be impossible to stop."
