The dramatisation of the Who Wants To Be A Millionaire? cheating scandal has captured the nation's attention this week but there have now been developments in the real life case as new analysis of the coughing in the case will call into question the convictions of Charles and Diana Ingram, according to their lawyers.

Quizhas seen the couple's journey to the programme and their high-profile 2003 court case told over a three-part series which is set to conclude on Wednesday evening.

The husband and wife were found guilty of scheming their way to the top prize of £1 million in a case that saw them deny a single charge of procuring the execution of a valuable security by deception.

Both Charles and Diana also received suspended jail terms after being found guilty.

The ITV show has depicted how Charles (Matthew Macfadyen) was quickly suspected of having cheated as those working on the show pointed to coughs from the audience indicating the correct answers.

Now, lawyers for the Ingrams are working on the submission of legal arguments to the Court of Appeal before the end of the year.

Their criminal defence solicitor Rhona Friedman argues that technological advances mean new analysis of the coughs that tipped off Charles to the right answer will cast doubt on the safety of their convictions.

Their legal team claim other coughs made by Tecwen can be identified along with coughs made by other members of the audience who they say were audible at other significant points.

They also claim that recent investigation shows that the integrity of the audio evidence of coughing given to the jury at trial may have been compromised.

Sian Clifford is portraying Diana in the series, while Michael Jibson plays Tecwen.

Charles himself has been sharing his thoughts on the drama via his Twitter account.

He's described the series as "terrifyingly accurate" as well as "horribly cringeworthy".
