Help For Heroes has said it will not accept money from anyone donating to the charity "to promote their own political agenda".
A statement said this was because Help for Heroes "is a non-political organisation".
This evening, working with the assistance of JustGiving, we closed down a fundraising account which we believe the English Defence League intended to use to donate money to H4H.
We acted swiftly to achieve this, and would like to make it clear that we will not accept donations from organisations who attempt to use Help for Heroes to promote their own political agenda.
Like everyone, we were shocked by the murder in Woolwich. Like everyone, we just want to help our wounded servicemen, women, veterans and their families.
We hope that everyone who cares passionately about this important issue shows that support in a unified and dignified way.
