When do LB need to extend their bid by?

they have stated that they will advise their Status of Conditions on or before tomorrow 27 June.
last time L/B notified the Status of Conditions the day before their stated notification date.

So they may well make their latest statement re Status of Conditions - ie TODAY. If not today, then tomorrow 27th June.

Last time when they made their notice of S-of-C they also advised the Extension of the Bid.

Thus we may well also get Notice of an Extension today.
