The family investment firm of Mexican billionaire Carlos Slim raised its stake in BT Group PLC to 4.3%, according to a Tuesday regulatory filing by the UK telecommunications company.
Slim’s Mexico-based Control Empresarial de Capitales SA de CV had previously disclosed a 3.2% stake in June.
Shares in BT rose 1.9% to 142.30 pence as of 9:08 a.m. in London.
Slim, 84, is the world’s 17th-richest person, according to the Bloomberg Billionaires Index. The Mexican tycoon made the bulk of that fortune from America Movil SAB de CV, the largest mobile operator in Latin America. Separate from Slim’s family investment firm, America Movil is also Telekom Austria AG’s biggest shareholder and owns a stake in Dutch carrier Royal KPN NV.
