She's a wet lettuce, we should send Boris in to baffle and bewilder him.
In all seriousness, all news channels are reporting that the UK now refuses to share any intel with the USA unless there are cast iron assurances it won't be leaked. The Manchester Met have also said they are not allowing anymore info about the MEN Arena attack to be shared with any US intelligence agency.
Obviously all this is subject to change, but at the very least it is a major embarrassment for Trump while he is on his G7 and NATO tour. I do think he will spin it to his favour though and he will just blame it on the people who have been leaking stuff about the Russia connections. Both Trump and the GOP will now start a witch hunt for those involved in leaking classified information. I doubt it will hurt Trump much more than annoying him that it will be brought up in front of him a few times over the coming days.
