Karime Macías, ex-wife of a state governor, is wanted for allegedly pilfering nearly £5m of public money and now lives in London

The Mexican president, Claudia Sheinbaum, has said her government will send a formal letter of complaint to officials in the United Kingdom after the wife of a former governor wanted for allegedly pilfering £4.8 million of public money was granted asylum in Britain.

Karime Macías, ex-wife of jailed former Veracruz governor Javier Duarte, is wanted for extradition to Mexico for allegedly siphoning millions from the state welfare office, but has reportedly spent the last few years in London.

“How can a woman accused of fraud and corruption be granted asylum?” Sheinbaum asked. “Today we are sending a letter with this position.”

Neither the British embassy nor Macias’ lawyer responded to a request for comment. The Home Office said it does not comment on individual cases. Macías’ asylum in the UK was first reported by Mexican news outlet N+.
