He has set up a complicated artificial structure which avoids the normal rule within companies house. His main vehicle is a so-called limited partnership, called ‘Windrush Ventures No 3 LP’.

Thanks to a gap in the Whitehall regulations, this entity is not required to publish any accounts. Such partnerships must normally disclose figures, or face criminal penalties.

Blair sidestepped the rules by inserting a second partnership as one of the notional partners, in a way the regulations do not cover.

This second partnership, Windrush Ventures No 2 LLP, is a so-called limited liability partnership, a type of entity only invented in 2000, which the rules have not been updated to mention.

The LLP in turn controls Blair’s operating company, called Windrush Ventures Ltd, which runs his Mayfair office in Grosvenor Square.

The perfectly legal structures Blair has set up to achieve secrecy are so complicated that they have previously baffled analysts.

They involve 12 different entities, six in the Windrush structure and another half-dozen in a more recent parallel structure called Firerush.

Blair’s spokesman told us: “This has been done on the basis of legal and accountancy advice throughout.” He called the structures “simply an administrative vehicle established in order to allow Mr Blair’s office sensibly to administer his different projects”.

One name involved is Blair’s lawyer Alexandra Harle, of solicitors Bircham Dyson Bell.

While the law requires Blair to publish limited accounts for parts of the Windrush entities, the finances of the master-partnership remain a secret. More than £6m can be seen to have cascaded down from the partnership into other companies. But details of the full revenues remain hidden.
Blair loves breaking and bending the rules wherever he can. To date he’s got away with it all. Even mass murder. But for how long?
