Oh flip, I spoke too soon.
The continuation of this series in a new weekly puzzles pull-out was cut and dried until today, but I’m sorry to say there’s a postponement. It’s actually got nothing to do with puzzles, rather some other content that's encountered some kind of technical issue, so we can’t see the GK Jumbo series starting until October at the earliest (it’s likely to be later than that but, fingers crossed, we’re not talking about a delay beyond the end of the year).
A bit disappointing, but the ed does at least have a healthy stock of Jumbo puzzles ready to go, and there are a couple more to run this month.
