petrochina perhaps?

I know that this theory is a longshot but here goes anyway:-

Cue has held up the farm-in announcement because of
PetroChina's share ownership of Cue so that PetroChina's identity could be kept secret until the FIR approved the takeover of Arrow. ("FIRB gives Shell and PetroChina the nod over Arrow bid", AFR p14, 6th April)

It simply wouldn't look good for two PetroChina deals to be before the FIRB at the same time.

If this is so then we can expect a Meo ann. soon!
