Should political lobbyists be allowed to become MPs?

“Owen Smith, who now faces Jeremy Corbyn in the Labour leadership battle, worked as a lobbyist in the pharmaceutical industry for five years before becoming the MP for Pontypridd in 2010.

After working for the US giant Pfizer, Smith moved to the controversial biotech firm Amgen in 2008. At the time, Amgen was battling an investigation into one of its most successful anaemia drugs, Aranesp.

Amgen was ultimately fined $762m for illegally promoting the drug to cancer patients in a way that increased the likelihood of their deaths. Amgen was hit with the fines after it emerged that the California company was “pursuing profits at the risk of patient safety” as it promoted a non-approved use of Aranesp.

Smith was in charge of corporate affairs, corporate and internal communications and public affairs at the British division of Amgen while the biotech company was being investigated.

The main whistleblower on Aranesp filed her case against Amgen in 2006, sparking a US investigation that took several years to conclude. The whistleblower also claimed that Amgen systematically overfilled vials of the drugs, when selling them in America, which enabled doctors to “pool” the excess amounts.

The doctors were then encouraged to bill Medicare and private insurers for the use of the excess drug, creating a system of “liquid kickbacks” according to one lawyer on the case.

Amgen also produces a drug called erythropoietin – better known as EPO – which it produced under its Epogen brand name. Epogen was connected to the international cycling scandal, which involved cyclists such as Lance Armstrong. …”

David Cameron was “Director of Corporate Affairs” at Carlton TV (i.e. a lobbyist):

In July 1994, Cameron left his role as Special Adviser to work as the Director of Corporate Affairs at Carlton Communications. Carlton, which had won the ITV franchise for London weekdays in 1991, was a growing media company which also had film-distribution and video-producing arms. Cameron was suggested for the role to Carlton executive chairman Michael P. Green by his later mother-in-law Lady Astor. Cameron left Carlton to run for Parliament in 1997, returning to his job after his defeat.

and our own dear Hugo Swire had a similar job at the National Gallery:

“He was a financial consultant, then became of Head of Development for the National Gallery, then Director of the auction house Sotheby’s directly before his election from 1996.”
