22 Jun 1483 St Pauls Cross: The Princes of the Tower described as Illegitimate
Robert Stillington Bishop Bath and Wells, had advised Richard, Duke of Gloucester, future King Richard III, that he, Stillington, had officiated at the wedding of Edward IV and Eleanor Talbot before Edward's marriage to Elizabeth Woodville making the subsequent marriage bigamous and their children, therefore, illegitimate. Since George York 1st Duke Clarence had been attainted his children were ineligible for the throne and therefore, Richard, Duke of Gloucester, was King Edward IV's rightful heir. Ralph Shaa, half-brother of the Mayor of London, preached the new found illegitimacy of the Princes in the Tower at St Paul's Cross.
Ralph Shaa preached the bastardy of Edward IV's children by Elizabeth Woodville including Edward V being therefore ineligible to be King.
26 Jun 1483 Richard III elected King by the Three Estates
Was it a usurpation of Edward V? Not necessarily. If Robert Stillington was being truthful and King Edward IV's marriage to Elizabeth Woodville was bigamous then the children were illegitimate and excluded from the succession; Richard III was the lawful heir to the throne.
In both the previous usurpations, Edward II King England and Richard II King England, the Kings were forced to abdicate. In the case of Richard III Edward V was regarded as ineligible for the succession so not required to abdicate; Edward V wasn't King because he was illegitimate. The argument rests solely on the word of Richard Stillington. It is worth noting that Stillington had been imprisoned by King Edward IV in 1478 for some unknown reason; the same that George York 1st Duke Clarence was executed by his brother, the reason for which is unknown.

1484 Titulus Regius
The Act of Parliament by which Richard III justified his usurpation of King Edward V. Richard described, on the evidence of Bishop Stillington, how his eldest brother King Edward IV was precontracted to Eleanor Butler and, as a consequence, his marriage to Elizabeth Woodville was invalid and, therefore, the children of the marriage, were illegitimate and, therefore, not eligible for the succession.
The only evidence of the precontract was the word of Bishop Stillington. He is vague insofar as he doesn't specify when or where. He only confirms, conveniently, that he was the only witness.
Titulus Regius doesn't describe when the pre-contract was supposed to have occurred. Eleanor Butler was born around 1436. She was married at 13 to Thomas Butler. King Edward IV was born 1442 so he would have been around six at the time of Eleanor's marriage. It is hardly credible that Edward would have entered into a pre-contract on his own volition (his father was in France) around the age of six?
Eleanor's husband died sometime before Mar 1461. Edward married Elizabeth Woodville in 1464. There is then a window of three years during which Edward may have been precontracted. The position is further confused by Eleanor having been one of Edward's mistresses for a long period.
On the accession of King Henry VII Titulus Regius was repealed and all copies destroyed. Fortunately, one copy survived.
