(Reuters) - UK's John Wood Group said on Wednesday its board has decided to engage with Sidara on its sweetened takeover proposal and grant the Dubai-based engineering and consulting firm access to due diligence materials.

Last week, Sidara raised its proposed takeover offer for the British oilfield services and engineering firm for the third time, saying that the cash offer of 230 pence apiece was its "final offer".
