Sajid Javid has admitted he previously held non-domicile tax status and kept money in an offshore trust.
Amid an ongoing row over Rishi Sunak's wife's non-dom status, the Health Secretary came clean about his own use of the scheme before entering Parliament in 2010.
Mr Javid also admitted to benefitting from an offshore trust when he worked for Deutsche Bank but said he voluntarily "collapsed the trust" when he became a minister in 2012.
