The Charity Commission has found a Brighton mosque to be “poorly managed” and disqualified a trustee during an inquiry sparked after a former trustee was convicted of encouraging terrorism.

The regulator opened the probe into Brighton Mosque and Muslim Community Centre, locally known as Dyke Road Mosque, in August 2022 over concerns of failures to resolve an undisclosed dispute that was found to have damaged the charity’s management.

The row came after former trustee Abubaker Deghayes was convicted for encouraging violent jihad in a speech to around 50 people including children at the mosque on November 1 2020.

At least one trustee was also present at the speech after evening prayers, the Charity Commission said, who did not intervene or attempt to minimise the impact of the content of Deghayes’s actions.

Deghayes, of Saldean, East Sussex, was jailed for four years at the Old Bailey in April 2022.

In inquiry findings published on Wednesday, it concluded the charity was “poorly managed” and there was “misconduct and/or mismanagement in the administration of it”.

The regulator added: “The Commission’s intervention and the appointment of the interim manager were necessary to restore proper governance and administration to the charity.

“A new board of trustees have been appointed to run the charity, which the interim manager identified after a full and thorough recruitment exercise.”

The interim manager took control of the charity’s finances, including cash donations of more than £17,000.

The inquiry also disqualified former trustee Karim Aboutayab on July 10 last year, for four years and six months after finding he had a “greater culpability” for the mismanagement discovered in the charity’s affairs.

This included using an “inflammatory” tone towards others which contributed to the dispute’s escalation, and failing to file the charity’s annual accounts on time.

The Charity Commission first assessed concerns at the charity after Deghayes was charged for encouraging terrorism in July 2021, and

later issued an official warning after deciding then-trustees knew or should have known about the risk he posed, in May 2022.

Head of inspections at the regulator Joshua Farbridge said: “Abusing a charity to encourage terrorism is a grave breach of public trust and we expect all trustees to take steps to ensure their charities cannot become safe havens for terrorist or extremist views.

“While the earlier criminal conviction was outside the scope of our inquiry, what occurred at Brighton Mosque and Muslim Community Centre demonstrates how serious disputes within a charity can not only severely impact its running and reputation, but leave a charity unprotected from the risk of exploitation by those with malign intentions.”

Brighton Mosque and Muslim Community Centre has been contacted for comment.

The Charity Commission has launched a new inquiry into a south London church which was found to be selling a coronavirus “plague protection kit”.

Bishop Climate Wiseman, head of the Kingdom Church in Camberwell, claimed earlier this year that the £91 small bottle of oil and piece of red yarn would protect people against Covid-19.

Media reports about his claims led to an investigation by the charity watchdog in April, resulting in the link to buy the kits being removed.

But the commission has now launched a new inquiry into the church, which is registered as a charity, over concerns about its management and finances.

The commission said it had examined the charity’s records, and was “concerned” about the accuracy of the information provided with regard to its income and expenditure.

The new probe, which was launched on August 7, will examine the charity trustees’ compliance with their legal duties around its administration, governance and management.

This will include an examination of its relationship with a connected organisation called Bishop Climate Ministries, which the charity claimed was responsible for the sale of the “plague protection kits”, the commission said.

Helen Earner, director of regulatory services at the Charity Commission, said: “Charities should be organisations that people can trust. Many will have been concerned by allegations about this charity’s activities in relation to Covid-19, and so it is right that we, and others, have intervened.

“Our own examination into The Kingdom Church GB has identified further concerns that require investigation, which is why we have now opened an official inquiry.”

In a blog post earlier this year, Bishop Wiseman claimed his concoction of cedar wood, hyssop and scarlet yarn acts as “an invisible barrier to the powers of darkness”.

He wrote: “It is by faith that you can be saved from the coronavirus pandemic by covering yourself with the divine plague protection oil and wearing the scarlet yarn on your body.

“That is why I want to encourage you, if you haven’t done so already, to get your divine plague protection kit today!”

He told the PA news agency in April that the church had sold more than 1,000 of the kits.

“This is based on the Bible – I’m a Christian and there is a way that the Bible says to protect us from plagues,” he said.

He previously insisted that the church was not selling the kits, and that the price tag was just to cover the cost of the ingredients, yarn and postage and packaging.

Bishop Wiseman said at the time that his church was not telling people to ignore the Government’s advice.

The Charity Commission said it would continue to work with Southwark Council Trading Standards’ investigation into the sale of the kits.
