Q: What is the political backdrop?
The mid-1990s were the final years of socialist president François Mitterrand's long period in office (which consisted of two terms, from 1981-1995). The Centre-Right opposition led by Jacques Chirac, head of the Gaullist Rassemblement pour la République (RPR) party, won the parliamentary elections in 1993. President Mitterrand was thus forced to have a government and prime minister from the political right.

Q: So where did Balladur's election war chest come from?
That is a key question. On April 26th,1995, after Balladur was eliminated in the first of the election's two rounds,10.25 million francs (about 1.5 million euros) were deposited into his campaign account in Paris in large denomination notes.
Balladur's team say the money came from collections at party rallies and from the sale of items such as T-shirts, a view dismissed by investigators working for France's highest constitutional authority, the Constitutional Council. Another theory was that the money came from

The third theory - central to the Karachi affair - is that the money came from the retro-commissions linked to the sale of three submarines to Pakistan.
Q: What is the difference between 'commissions' and 'retro-commissions'?
During the 1990s, when the submarine sale was concluded, it was still legal for French arms firms to pay 'commissions' - in reality bribes - to foreign dignitaries and decision-makers to persuade their country to buy defence equipment from France rather than another country. They could even be offset against tax. This was widespread, not limited to France. An OECD agreement among member states in 2000 finally outlawed the practice.
However, in 1994, it was already illegal for any of those commissions (i.e. paid to bribe local officials) to be channelled back into France. These are what are known as retro-commissions.
Q: Where are the Balladur retro-commissions said to have come from?
In 1992, before Balladur became prime minister, France was negotiating to sell Pakistan three Agosta-class submarines. By the summer of 1994, the deal was all but signed for a total value of 826 million euros (the value negotiated then in French francs). However, at the last minute, Balladur's government insisted that two

Q: Who were these new intermediaries?
Lebanese businessmen Ziad Takieddine and Abdulrahman El-Assir. Takieddine describes Sarkozy as a "friend".
Q: When did stories of these illegal retro-commissions first emerge?
In political circles, almost immediately. Chirac's camp knew that his rival Balladur had no party political funding and there were rumours that the latter's campaign money came via arms deal commissions. In 1995, the newly-elected President Chirac ordered the examination of arms deal commission payments authorized when Balladur was prime minister. Chirac ordered that the payments be immediately halted in those where retro-commissions were found or believed to be involved.
Chirac's camp has presented this as an attempt to clean up public life. However, Chirac's own track record suggests probity was far from the top of his agenda. What has been widely suggested in the media and by a number of politicians, but unproven, is that it was bid to cut off the funds of the man who betrayed him and who could otherwise continue to represent a political threat. However, the fact that the Constitutional Council approved Balladur's election campaign accounts in 1995 - against the advice of its own investigators - helped prevent the stories becoming public.
It was only in September 2008, when Mediapart broke news of the existence of an internal DCN report linking the Karachi bomb attack to the cancellation of arms deal commissions, that the allegations began to emerge.
Q: What is the evidence for the retro-commissions?
