Local MP Alan Mak has paid tribute in Parliament to two Post Office Horizon campaigners from the Havant Constituency.
He spoke in the House of Commons during a debate on the Post Office (Horizon System) Compensation Bill and praised Malcolm and Lesley Simpson.
Mr Mak also secured thanks to the couple for their campaigning work from postal services minister Kevin Hollinrake MP.
Mr and Mrs Simpson used to run a post office.
The ITV drama Mr Bates v the Post Office has had a powerful impact and put the Post Office Horizon scandal firmly in the media and political spotlight.
Havant Constituency MP Mr Mak said: "Like Mr Bates, my constituents Mr and Mrs Simpson ran a village shop and post office that suffered from the faulty software.
"They have campaigned for compensation through the Justice For Sub-postmasters Alliance and Mr Simpson himself gave evidence at the public inquiry.
"Will the Minister join me in paying tribute to my constituents and their colleagues? Without their determination and courage, we would not be where we are today, delivering this Bill to support those victims."
Mr Hollinrake responded: "I thank my Honourable Friend for his intervention and I particularly thank Mr and Mrs Simpson for their work. Of course, a number of people campaigned so strongly on this tragedy.
"I pay tribute to his constituents and to many others like them who made sure we are here today, delivering justice and, indeed, compensation for those postmasters.
"Alan Bates’s case is one individual tragedy, but he is only one among many: over 3,000 people have suffered in some way as a result of this scandal.
"For some, that meant paying the Post Office money they did not owe. For others, it meant the loss of their livelihood, their home, their mental or physical health, or their family relationships.
"Too many have died before getting justice; saddest of all, some of those deaths were suicides. Each Horizon victim is a personal tragedy, and it is imperative that each and every one gets the justice and compensation for which they have waited too long."
