Paula Anne Vennells, CBE (born 1959), is a British businesswoman and Anglican priest. She was chief executive officer of Post Office Limited from 2012 to 2019. Under her leadership, the Post Office prosecuted hundreds of subpostmasters for fraud, despite knowing that the relevant financial discrepancies actually arose from computer errors for which the Post Office was responsible. According to Channel 4 and the BBC, this matter is the biggest miscarriage of justice in British history.
