I see Hizb ut Tahrir in the UK are continuing their old tactic of organising events under different names:

In a clear sign of what [Hizb ut-Tahrir, HT] have been reduced to, they’re now skulking around organising purportedly independent events at major mosques and misleading other Muslims about who they are – just to get them to turn up to events run by HT members. Oh dear.

I remember they used to organise events at my university under the Bangladeshi society or something similar, because not only had they had been banned by the university, they were not on best terms (for theological reasons) with the people who ran the Islamic society.
