A barrister has been reprimanded and fined £500 over tweets accusing his former colleague of a campaign of fabricating stories about antisemitism.

The Bar Standards Board said that Daniel Bennett had been sanctioned in relation to ‘inappropriate and offensive’ tweets sent between September 2018 and June 2019 from the account @arrytuttle towards the high-profile human rights barrister Adam Wagner.

The BSB did not specify that Bennett sent the tweets himself, but said he ‘allowed’ them to be sent and in doing so behaved in a way which was likely to diminish the trust and confidence in him and the profession.

Bennett had joined Doughty Street Chambers in 2009 but left in 2019 over his links to the Twitter account, which has been deleted. The account targeted activists campaigning against antisemitism in the Labour Party, including Wagner, also with Doughty Street Chambers.

The account, which had around 4,500 followers, accused Wagner of being a ‘lying propogandist who brings shame on our entire community’. It said that Wagner’s stories about antisemitism were ‘fraudulent’ and that left-wing Jewish people were targeted for factional political gain. One tweet in relation to Wagner and two other barristers had described them as 'an awful threesome'.

Bennett, called in 2000, has 21 days to appeal the BSB decision. The ruling did not give any context about the misconduct or say whether mitigation had been offered or accepted.

It was reported previously that Bennett had apologised for any offence caused by the account and said he did not support or endorse any attacks on Wagner and others.

Wagner said in 2019 that the account had ‘waged a campaign of anonymous abuse and harassment against me and others involved in the Labour antisemitism issues’.

Following the BSB decision he tweeted: ‘This has all been incredibly stressful as you might imagine so I’m not going to say anything more about it for now.’
