Please find below a statement from Leave.eu posted on Facebook.
The Supreme Court march is OFF.
We have been genuinely humbled by the response we have had to our plan to hold a rally outside of the Supreme Court.
Our call centre has been inundated with calls from dedicated supporters offering to help out in any way they can with thousands of members already booking their accommodation and travel even before any details were confirmed.
Unfortunately, our attention has been drawn to the possibility of far-right extremist groups hijacking what we intended to be a peaceful protest of the High Court’s decision on Article 50.
Furthermore, we have received information that several pro-EU groups were planning a counter protest and our fear is that things could get out of hand.
The safety and well-being of our supporters is of paramount importance.
With this in mind and after much consideration, it is with regret that we have had no other option but to cancel the event.
There are bigger fights ahead of us with the future of Brexit.
Those who wish to subvert democracy and refuse to respect the referendum result are busy behind the scenes, building a new campaign to block Brexit.
We urge all of our supporters to channel their frustration into helping us fight this when the time comes.
Please distribute to all members and Brexit supporters.
