Arday said the criticism had gone too far and hurt him and his loved ones. He made this statement after weeks of allegations.

Jason Arday carried the Olympic Flame in London in 2012.

A group called the Good Law Project supported Arday and said the allegations were unfair. Many academics and politicians agreed with them.

Arday's story is one of overcoming difficulties. He was non-verbal until 11 and illiterate until his late teens. He tells his story in a new book.

Someone named Nathan Cofnas questioned Arday's qualifications last month.

A newspaper found parts of Arday's PhD thesis were very similar to another researcher's work. This was reported on July 24.

The media also questioned Arday's charity claims, including running many marathons.

Arday said he raised the money with help from others over 20 years. He couldn't name them due to agreements.

Cambridge University first supported Arday, saying his PhD university had already looked into the allegations.

But then Cambridge decided to investigate.

The university said it was looking into new information about Arday's qualifications. They won't comment until it's done.

A newspaper said Cambridge acted after being given new evidence that some of Arday's research was false.

Arday denied plagiarism but admitted to some mistakes in an interview.

Arday defended himself in his resignation statement, saying he still believes in scholarship.

He said his decision was not because he accepts the criticism, but because he can't take it anymore.
