A pedestrian walks past an advertisement for Reliance Communications in Mumbai yesterday. Billionaire Ambani brothers Mukesh and Anil, who fought a very public feud for spoils of their father’s business empire, signed on Tuesday a $220mn telecom deal in the first tangible sign of a corporate reconciliation. Under the deal, Mukesh’s Reliance Jio Infocomm will share the optic fibre network of Anil’s Reliance Communications for 4G telecom services. The companies said they could co-operate further in future.
