Looks like there were two deferred publications yesterday, each with a value over £340k...! That's two massive trades relative to recent volume. One trade placed after 5pm and another deferred publication from 3:37pm yesterday.
I suspect there is a lot to do if they are firing up the PR machine too... Lot's of info to collate and an obligation to release it once it's ready so as not to fall foul of market regulations...
Personally I wouldn't choose to release during a holiday period... especially following a sunny bank holiday - they are like hens teeth!
