German carmaker Volkswagen said a scandal over falsified vehicle emission tests in the United States could affect 11 million of its cars worldwide. Volkswagen said it would set aside 6.5 billion euros ($7.3 billion) in its third-quarter accounts to help cover the costs of the biggest scandal in its 78-year-history, blowing a hole in analysts' profit forecasts.
Following are responses from other national regulators.
Australia's competition regulator said it was looking into whether Volkswagen had misled consumers over its emissions claims after the German carmaker admitted cheating on U.S. pollution tests.
The European Commission urged all member states to investigate into how many cars use illegal "defeat" devices to cheat emissions tests in light of the scandal at Volkswagen.
EU regulators said they were in contact with Volkswagen and U.S. authorities following the car-maker's admission it had rigged emissions tests, and called on member states to rigorously enforce the relevant law.
Britain's transport minister said the government would work with vehicle manufacturers to ensure that the use of emissions-cheating software was not being used widely in the industry.

France will carry out testing to establish whether vehicles on its roads are equipped with banned software of the kind used by Volkswagen in the United States to trick emissions tests, the country's environment minister.

Italy will test 1,000 cars from all the VW brands sold nationally, its transport minister said.
Italy has also said it would open its own investigation into whether Volkswagen had cheated in diesel vehicle emissions tests in Europe as it did in the United States. The Italian Transport Ministry said it had sent a letter to Volkswagen and the main emissions tester in Germany to ask "if the anomalies found could also have been conducted on vehicles sold and tested in the European Union".
