Nicolas Sarkozy, the French President, is going to be on national television in the middle of a scandal that involves the L'Oreal cosmetics fortune that seemed to have destabilized his Government.

Sarkozy will try to suppress the political donations scandal on Monday night on France-2 television, which comes after the ruling UMP party lost a Parliamentary seat in Sunday's by-election.

The many-sided scandal includes charges by an ex- accountant for Liliane Bettencourt, L'Oreal's heiress, that she gave cash illegitimately to Sarkozy's Presidential election crusade.

Sarkozy has rebuffed all the assertions, which have not been proven.

Claire Thibout, the ex- accountant, said that she had been involved in withdrawing $200,000 in cash that was to be given to Eric Woerth, the nation's labor minister, in unmarked envelopes as a gift to Sarkozy's 2007 election campaign.

An official inquiry cleared Woerth on Sunday of taking undue advantage of his position to guard France's richest woman from a tax inspection, but critics said the account did not remove qualms of a conflict of interest.

Woerth was treasurer of Sarkozy's 2007 Presidential campaign, who remains treasurer of the UMP and served as budget minister who was responsible for tax affairs, and his wife worked for Bettencourt's wealth manager.
