Australian company says it is frustrated that UK property website has refused to engage over £6.1bn offer

Rightmove has rejected a third bid from Rupert Murdoch’s REA Group and said the offer was “unattractive” and undervalues the UK’s largest online property portal.

On Wednesday Rightmove confirmed that its board had “unanimously rejected” the non-binding cash-and-shares offer put forward on Monday, which valued the company at £6.1bn.
