This is from 2021 but does show the problem we have here in London (they all seem to live near me never mind near our very large jewish and hindu communities in North London).
"An in-depth investigation conducted by TPS two years ago and published in December 2019 revealed the existence of a “London Hamas gang” which was called by French intelligence “Londonistan.” The investigation revealed that Hamas was well entrenched in Britain, had established institutions and foundations there, carried out extensive diplomatic activities, enjoyed the Muslim Brotherhood’s well-oiled communication system, forged ties with Labour activists, and organized flotillas to the Gaza Strip with people who had been deported by Israel on board.
The main subjects of the investigation were Zaher Birawi, Muhammad Zualha, Azzam Tamimi, Ibrahim Hamami, Anas Tikriti, Kamal Hawashh, Adnan Hamidan, Kazem Zwalaha, Haft Carmi and others, all Hamas operatives and the Muslim Brotherhood, as well as the organizations mentioned in the investigation.
Zaher Birawi is probably the most important of the Hamas operatives in London and holds the “London file” in the organization. He engages in propaganda activities against Israel in Britain and is also involved in “legal warfare” against the Jewish state. Most importantly, he is the one who had the closest ties with former Labour Party leader Jeremy Corbyn and pushed for Corbyn’s election.
Like many of his colleagues in Britain, Birawi is not a mere civilian but is part of the leadership of Hamas and the Muslim Brotherhood there. Many of his colleagues are known to the Israeli defense establishment, and the institutions in which they operate and their members have been banned in Israel. Birawi has visited the Gaza Strip many times and was photographed alongside the local Hamas leadership while wrapped in its flag." https://tps.co.il/articles/londonistan-hamas-base-of-operations-in-england/
