Britain on the cusp of considering officially the entire Hamas as a 'terrorist organization'
Because it can't tell which parts are political and which militant. Hamas does have a 'political wing,' though.
US, Canada and EU already designate Hamas a terrorist group.

"I think it's actually a fallacy to consider military and political separate. The political wing is integral in helping the military wing in terrorist organizations." - Anne Herzberg
Included in the political move, if it passes (and Boris is considered to be pro-Israel) is criminal liability including jail punishment for people who support Hamas (as a 'terrorist organization'). This will affect all groups doing fundraising, meetings, media coverage.

She said England's Palestinian community of about 5000 would not any longer be able to speak freely about this issue.
