And given that the article points out that a Tunisian official was taken in for questioning in Rome, the Tunisian embassy might play a role in this operation--enquiring minds want to know!
"There is still a hidden controller/handler in England."
Maybe. Typically, the bomb master flies in to check the work, then flies out a day or two before the attack(s). The chemist caught in Egypt may have filled this role. The guy tased on Thursday apparantly talked, giving the addresses for the arrests on Friday. If true, then under a strict cellular structure, he must be the onsite supervisor, given that no-one at the bottom level should know anyone else at that level's personal information.
Not conclusive, but strong enough to offer possibilities for alternative structural arrangements not easily dismissed.

Brother, internet node, embassy official, these point to AQ's support operations, which are, according to AQ doctrine anyway, kept strictly separate from AQ's operational branch.
Most likely avenues for progress in rolling up additional levels of hierarchy, from this bunch, look to lie with taser boy, and if the London cell was following AQ doctrine, will probably point overseas.
