EU competition regulators have suspended their investigation into Fiat Chrysler and Peugeot maker PSA's proposed merger while waiting for the carmakers to provide requested data.
"This procedure in merger investigations is activated if the parties fail to provide, in a timely fashion, an important piece of information that the Commission has requested from them," the European Commission said today.
"Once the missing information is supplied by the parties, the clock is re-started and the deadline for the Commission's decision is then adjusted accordingly," the EU competition enforcer said.
The previous deadline for the EU's decision was November 13.
The Commission is investigating whether the deal to create the world's fourth-biggest carmaker would hurt competition in small vans in 14 EU countries and Britain.
