After the 2015 general election, Cable turned down an offer of a peerage from Nick Clegg in the dissolution honours list. Former Lib Dem MPs David Laws, Simon Hughes and Danny Alexander are also understood to have turned down the offer.
Cable served in the Liberal Democrat Shadow Cabinet as spokesman on trade and industry from 1999 to 2003. Followed by a role as shadow chancellor from 2003 to 2010. He was deputy leader of the Liberal Democrats from 2006 to 2010. 
Outside of politics, Cable worked as treasury finance officer for the Kenyan Government between 1966 and 1968. From 1968 to 1974 he was a lecturer in economics at Glasgow University. He then worked in a range of senior economic and foreign policy roles, before becoming Shell International’s chief economist in 1995. 
Having left his post as secretary of state after the last general election, Mr Cable sought the advice of the Advisory Committee on Business Appointments (ACOCA) regarding a number of new appointments.
Provided that he serve a two year lobbying ban from his final day in office and that he did employ and privileged information he accessed while in government, Cable was permitted to take on the following positions;
- Professor in practice at the London School of Economics
- Governor of the Richmond Adult Community College (RACC)
- Panel member of DBA Speakers
- Board member of Health-Connected 
Cable attended Nunthorpe Grammar School before going to York and Fitzwilliam College, Cambridge, where he studied natural science and economics and was President of the Union. He then studied for a PhD at Glasgow University.
