Birmingham and the West Midlands are under-represented on shadowy bodies which spend £123 billion of taxpayers' money each year, a major new study has warned.
An investigation into who really runs Britain found the quangos which control many publicly-funded services are dominated by London and the South East.
Bodies such as the Environment Agency, the Learning and Skills Agency and the Big Lottery Fund make decisions which affect all our lives, but there is no attempt to ensure they are representative, the study found.
It was published by the New Local Government Network, a think-tank which is close to Gordon Brown.
The report's authors were Chris Leslie, a former Labour MP who managed Mr Brown's campaign for the Labour leader-ship, and researcher Owen Dallison.
It warned that quangos control a fifth of all public spending, more than local councils, but the public knew little about them or the people who controlled them.
While councillors are chosen in hard-fought election campaigns surrounded by publicity, quango board members were typically appointed by Government politicians, and they were not accountable to the public.
The think-tank carried out a survey of 1,000 quango board members, and compared the population of each local authority to the number of quango leaders who were residents.
It found that more than half lived in London or the South East.
And more lived in just four London boroughs - Camden, Westminster, Islington and Kensington & Chelsea - than in the whole of the West Midlands.
The boroughs have a population of 824,000 and are home to 148 board members, while the West Midlands region has a population of more than five million and is home to 47 quango executives.
Even taking London's large population into account, the study found the number based in the capital was two-and-a-half times what it should have been to be representative of the country as a whole.
By contrast, the West Midlands has half the representation it should, based on its population.
Even within the region, the picture was mixed. Worcestershire and Herefordshire were over-represented, but Birmingham was under-represented. Other major cities in the United Kingdom, including Liverpool, Manchester and Leeds, are also under-represented on the region's quangos.
The worst offenders are cultural bodies such as the National Portrait Gallery, the British Council, the British Museum and Channel Four, which is run by a Government-appointed panel.
All are dominated by Londoners. Although they run organisations which are based in the capital, these are supposed to be national institutions.
Mr Leslie said: "While London and the counties immediately surrounding it are home to over half of all quango board members, there are, in contrast, vast swathes of England with apparently no voice on our public bodies. Looking at England as a whole, within each region there are clear concentrations of power, postcodes which are clearly more likely to produce the 'great and good' for seats on quango boards.
"We suspect that the poorer the area you live in, the less likely you are to climb to the heights of quango board membership."
In the short term, quango vacancies should be publicly advertised with open and fair selection procedures, the report said. In the longer term, quangos should be abolished wherever possible, with their powers given to elected local councillors instead.
The report says: "We believe that many national public bodies could be better composed if they properly reflected the nations, regions and counties of the UK.
"The next wave of local government reforms should therefore consider whether, on the principle of subsidiarity, some of the functions currently vested with national quangos might be better undertaken either at regional or preferably at local government level."
Mr Leslie was the Labour MP for Shipley, Yorkshire, from 1997 to 2005, and a Minister in the Department for Constitutional Affairs from 2001 to 2005.
He was Gordon Brown's campaign manager in Labour's leadership election last year, although Mr Brown was eventually appointed without a contest after no other candidate came forward.
