July 29 (Reuters) - Telecom Italia (TIM) reported second-quarter core earnings broadly in line with expectations on Wednesday, as growth in its Brazilian unit and enterprise division accompanied a return to growth in its domestic market.

The results are the first since TIM's board on July 18 unanimously approved a takeover offer from its largest shareholder, Poste Italiane, in a deal valued at more than 13 billion euros that aims to create a national telecommunications champion.

The former phone monopoly's earnings before interest, tax, depreciation and amortisation after leases (EBITDA-AL) for the three months to June 30 rose to 998 million euros ($1.14 billion), compared with a company-provided analyst consensus of 995 million euros.

Domestic revenue returned to growth during the quarter, while Brazil and TIM Enterprise continued to support the group's performance.
