Toyota-owned carmaker Daihatsu has closed all four of its plants until the end of January, after admitting it had falsified safety tests.

Daihatsu admitted that it had been manipulating safety tests on 64 makes for three decades.

Its headquarters in Osaka, Japan was the last to close, on 25 December.

The scandal puts in jeopardy 9,000 workers in the country and could affect global car giant Toyota’s reputation.

Of the 64 models involved in the scandal, 24 are sold with Toyota branding.
