Blackland PR has looked at the backgrounds of our 121 MPs:
The study, by political researcher Geoffrey Miller and public relations expert mark blackham, researched and compared the career histories of all 121 Members of the current Parliament.
They found that business owners, agriculturalists and unionists have a falling share of voice in their traditional parties, and have been replaced by people with no specific career interests, or careers limited to government and politics.
Miller said 23% of National MPs had experience working in a business, and only 10% of Labour MPs had worked in a union.
“National is no longer dominated by business experience and Labour no longer by unions.
“In fact, the whole of Parliament is now dominated by generalists, people of no specific experience, and government specialists – people whose only experience is working for government or in politics.
This is not a good trend – the rise of the professional political class.
I've compiled this table from their data. The percentages add up to over 100% as some MPs have had multiple careers.
