LABOUR must “robustly scrutinise the detail” of Royal Mail’s takeover offer by Czech billionaire Daniel Kretinsky, Communication Workers Union (CWU) said today.

General secretary Dave Ward’s call came after it emerged the £5 billion bid will undergo a government probe, including into potential links with Russia.

“The contractual obligations negotiated between the failed current Royal Mail Board and Mr Kretinsky are not strong enough to protect workers, customers and the crucial infrastructure that Royal Mail provides for our communities and the economy,” he added.
