The plight of a post worker from the Amersham and Chesham constituency who was subject to a non-disclosure agreement (NDAs) was the focus of an address to parliament recently.

MPs had gathered to discuss the management culture of the Post Office and its ongoing scrutiny since the airing of the ITV drama 'Mr. Bates vs The Post Office' earlier this year.

Government’s business minister, Kevin Hollinrake, affirmed that those subpostmasters who had signed NDAs with the Post Office were free to discuss their situation with MPs and other authorities.

The drama series had highlighted the plight of hundreds of subpostmasters who were wrongly convicted of stealing.

These convictions followed a miscalculation by the Post Office's flawed Horizon accounting system, which erroneously showed a shortfall in their branches.

Some of these subpostmasters had signed NDAs when settling with the Post Office over their treatment.

Liberal Democrat MP Sarah Green directed attention to the case of one subpostmaster from her Chesham and Amersham area.

Her constituent had served the Post Office for over 30 years but was subject to an NDA.

According to MPs, details of the Horizon dilemma could have been unmasked "much earlier" if these agreements were not imposed.

The Post Office worker said: "As a member of the Post Office project team that delivered Horizon I, like many of my ex-project colleagues, was aware of the truth behind many of the points that the Post Office have been at great pains to hide or deny...The Post Office has used these non-disclosure agreements to ensure that current and ex-employees are effectively silenced."

During the debate, MP Ian Lavery criticised the treatment of subpostmasters, drawing comparisons with the German Nazi era secret police, the Gestapo.

Despite these criticisms and calls for transparency, Mr Hollinrake remained optimistic about the Post Office's changing methods.

Mr Hollinrake said: "I do believe today’s Post Office is different from the past, but restoring trust will take time and that does not mean that we are satisfied with the situation currently."

Parliament concluded that drawing attention to the issue remained crucial for the public eye and government.

SNP MP Marion Fellows said: "I don’t often compare myself to Arnold Schwarzenegger but ‘I will be back’."
