A former armed forces minister and staunch advocate of the military intervention in Iraq is topping up his MP's salary with up to £170,000 from other lucrative posts.

East Kilbride, Strathaven and Lesmahagow MP Adam Ingram has the highest declared outside earnings of any politician representing a Scottish constituency.

His five posts include a £55,000 berth with IT firm EDS, which was awarded a £4 million contract by the Ministry of Defence (MoD) when Ingram was still working in the department.

Ingram was armed forces minister in Tony Blair's government between 2001 and 2007, and was a strong supporter of the Iraq war.

He left government when Gordon Brown became prime minister, but has since topped up his income with a raft of directorships and consultancies.

As non-executive chairman of SignPoint Secure Ltd, an emergency communications firm, Ingram earns between £45,000-50,000 a year.

The MP also lands up to £25,000 a year for his non-executive directorship of Argus Scotland Ltd, a design and construction services company. He earns the same amount as a consultant to Argus Libya UK LLP, which is part of the same group as the Scottish firm of the same name.

Ingram also makes up to £55,000 a year as an advisor to Electronic Data Systems Ltd (EDS), which provides IT to the public and private sectors.

In 2005, EDS led a consortium which landed a £4 billion contract from the MoD to revamp its computer and information infrastructure.

The 10-year contract was won despite the company's well-documented problems handling the IT system for the Inland Revenue and the Child Support Agency.

EDS was also criticised in October after it lost the personal details of up to 10,000 armed forces personnel. The missing hard drive included the names and private details of half the armed forces.

Ingram also declares a non-executive post at the International School for Security and Explosives Education, which makes him up to £15,000.

Putting his lucrative outside interests together with his £63,291 MP's salary, Ingram can expect to earn up to £233,000 a year in total.

This figures excludes the £104,667 the MP claimed in expenses between 2006 and 2007.

Ingram's place as at the top of the declared-earnings league table for politicians representing Scottish seats is shown in the parliamentary register of interests.

Menzies Campbell, the North East Fife MP and former Liberal Democrat leader, earns up to £20,000 from his directorship at the Scottish American Investment Company plc.

Another one-time LibDem leader, Charles Kennedy, declares around £70,000 in outside earnings, mainly from journalism and after-dinner speeches.

Nigel Griffiths, the Labour MP for Edinburgh South and former government minister, has a non-executive post for The Jabbar Group and Public Interest Foundation, but does not list his remuneration.

Former defence minister John Reid, who worked with Ingram at the MoD, earns up to £50,000 in consultancy fees from security firm G4S UK and Ireland, while also acting as chairman of Celtic plc.

Ingram did not return the Sunday Herald's call.
