Singapore Post, the national postal operator, yesterday abandoned a controversial deal to buy a stake in a troubled local mobile phone repair company that had raised questions about conflicts of interest.

SingPost, which is 31 per cent owned by state-controlled Singapore Tele- communications, said it was cancelling the purchase of up to 29.9 per cent of Accord Customer Care Services (ACCS) for S$123m (US$74m) because ACCS was unable to fulfil its obligations under the terms of agreement.
