Akshata Murty may have avoided up to £20m in tax with non-dom status

Pressure grows on chancellor over tax affairs of wife, who pays 30,000 a year to be classed as non-domiciled

Rishi Sunak's wife has potentially avoided up to 20m in UK tax by being non-domiciled and pays 30,000 a year to keep the status - revelations that come amid growing political pressure on the chancellor.

Akshata Murty gets about 11.5m a year in dividends from a stake in an Indian IT firm and declares non-dom status, which allows people to avoid tax on foreign earnings, it emerged on Wednesday.
