Continuity mistake: As Victor and Mickey are talking in Victor's office, Victor has his feet placed on his desk. He then removes them and leans forward to speak to Mickey. In the next shot, his feet are suddenly on the desk again. (00:11:50)
Character mistake: When Mickey and Emma are trying to get access to the university labs, they claim they are working for Ofsted, and are investigating exam manipulation allegations. In fact, Ofsted have never been responsible for supervising/investigating universities - they only cover places of education up to the age of 18. Completely different organisations supervise universities.
Deliberate mistake: When Sam first meets Mickey (who is posing as a bank robber), Mickey says he needs Sam to state that he needs Mickey's help in robbing a bank, so if Sam turns out to be an undercover cop, Mickey can plead entrapment. This is a classic error. Entrapment only exists where a cop actively persuades a criminal to do something he otherwise wouldn't have done - which is not the case here. If Mickey as a con artist knows this (which is likely), it's a deliberate mistake, otherwise it's a factual error. (00:30:09)
Plot hole: When Albert, Mickey and Emma are trying to decide which nationality of millionaire Albert will pose as, they decide not to go with an English millionaire, since Albert at this point tries and fails to do a remotely convincing upper-class English accent. However, in many earlier episodes (such as "Gold Mine") he has no problems at all in putting on a convincing upper-class English accent.
Factual error: In the flashback scene to Whittaker senior's trial at the Old Bailey (which takes place in the late 19th or early 20th century), the judge in the trial is wearing a long, full-bottomed wig. This is completely incorrect - since the late 18th century, full-bottomed wigs have only been worn by judges on ceremonial occasions, not in court. At trials, judges wear short wigs instead.
