Four people, two of whom worked for the Ministry of Defence, have pleaded guilty in a high-level bribery and corruption case in Belfast. The case centred on the award of contracts worth £16.2 million for the supply of  CCTV services and equipment to the MoD through the payment of bribes. William Marks (55), who was MoD deputy senior commercial officer at the time, admitted accepting £66,500 in bribes from James McGeown (73), the owner of VIS Security Solutions. John Symington (56), a senior quantity surveyor for the MoD, pleaded guilty to four counts of corruption after accepting £18,000 from McGeown. Carol Kealy (53) admitted obstructing a police investigation by using a bank account in her name to process Marks's funds. She was given a conditional discharge. The other three defendants will be sentenced later this month.
