Four men have been jailed over a £6m NHS contract fraud described as "outrageous" by investigators.
Gavin Brown and Adam Sharoudi used their connections with senior health service employees Gavin Cox and Alan Hush to obtain lucrative telecoms contracts between 2010 and 2017.
An investigation into Oricom Ltd, established by Brown and Sharoudi, found Hush and Cox gave the firm "commercially sensitive information" in return for £88,000 worth of cash, gifts and holidays.
Oricom directors Brown, 48, and Sharoudi, 41, were jailed for seven and eight years respectively, while Hush, 68, and Cox, 60, were jailed for eight and six years.
Sentencing, Lord Arthurson said evidence given by each of the men was "self-serving, arrogant and mendacious", adding they had "subverted public trust in NHS management".
The group's crimes were only uncovered after the theft of two NHS-issued mobile phones, which led to thousands of text messages and emails being discovered on multiple laptops, computers and mobiles.
