MILAN, April 19 (Reuters) - U.S. investment company

KKR's proposed buyout of Telecom Italia's (TIM)

fixed-line access network will be decided by EU

antitrust regulators by May 30, according to a European

Commission filing on Friday.

The former phone monopoly said earlier on Friday that KKR

had sought approval from the EU competition enforcer for the

proposed deal.

The Commission can clear the deal with or without

remedies during its preliminary review or it can open a

four-month long investigation after the initial scrutiny if it

has serious concerns.

TIM said the confirmation it had received from KKR indicated

that the project was progressing according to schedule.

TIM has agreed to sell its domestic network to KKR for up to

22 billion euros ($23.5 billion) as part of a government-backed

plan aimed at cutting debt and relaunching the group.

TIM plans to finalise the deal around mid-2024 and any delay

could complicate the company's revamp.

Vivendi TIM's single largest shareholder with a 24%

stake, has criticised the network sale, questioning both the

price and the sustainability of the residual services business.

The French media group is fighting the sale in court.

The Italian government holds an indirect stake in TIM, which

has been weighed down by debt and has been battling fierce

competition.
