TAIPEI, Taiwan - The Presidential Office has confirmed that the first daughter's husband, identified earlier only as Tsai Pei-jan, is also former fashion model Allen Tsai.

Late Monday, the Presidential Office released the identity of the "first son-in-law," who had fallen subject to intense media speculation. Tsai Pei-jan is a Taiwan-born, US-raised investment banker who now lives in Hong Kong with first daughter Lesley Ma, according to spokeswoman Garfie Li.

He is also a former fashion model, according to media reports that the Presidential Office confirmed yesterday.

Tsai, born Aug 5, 1980, signed with US modeling agency Next in 2008 and has worked for Esprit, Gap and Levi's. Tsai has also appeared in editorial features for Italian Vogue and Vanity Fair, noted Chinese-language media The China Times, United Daily News and Apple Daily.

President Ma Ying-jeou authorised staff yesterday to confirm that Tsai Pei-jan is indeed Allen Tsai.

According to a Presidential Office aide, the president had kept the marriage private out of respect for his daughter and wife's wishes. On Monday, pan-green legislators raised concerns that the unknown son-in-law could jeopardize Taiwan's national security. The first family relented and released details at aides' suggestion.

Tsai has Taiwanese nationality and there is no national security risk to Taiwan, said an aide who asked to remain unnamed.
