Happens to us all.
A dispute resolution partner at Mishcon de Reya has apologised after he used his Twitter account to call Conservatives 'turds', 'knobs' and 'racist bigots'.
Louis Flannery QC, an arbitration expert, made the colourful comments while venting his frustration with his ideological opponents.
"You utter knob. You have zero understanding of constitutional law", the solicitor advocate told a member of the public who commented on the Supreme Court's ruling in favour of Gina Miller, a Mishcon client.
"What a nice person", responded the man. "Apparently a lawyer, so God help any clients if this is the attitude displayed."
Flannery told the whinger, "No mate. Just someone irritated by a goonish sycophant like you sucking up to a corrupt and inadequate PM and spreading drivel without bothering to check the facts or enquire what the judgment in Miller 2 was about. Anyone has the right to call you a knob in those circumstances".
The firm told RollOnFriday that an individual complained to Mishcon de Reya "after some tweets were sent by Louis Flannery QC in a personal capacity", but that the partner deleted them before the complaint was even made.
"As soon as he was aware of the complaint he apologised unreservedly, which was then accepted by the individual who was involved", said the firm.
Flannery turned his sights on Conservative voters in general during the Hartlepool by-election in May. When a poll showed the Tories taking the lead, left-leaning radio presenter James O'Brien asked, "What fresh hell is this?"
Flannery responded, "No fresh hell. Same old purgatory, full of thick selfish racist zenophobic [sic] bigots".
The Mishcon partner could have done with some more zen himself when Steve Baker, an MP and prominent Brexit cheerleader, tweeted, "I'm delighted after years of fighting for it we have axed the hated #TamponTax".
The QC retorted, "You really are an unspeakable piece of turd. Disgraceful".
Flannery was similarly disparaging when another Tory MP, Joy Morrissey, strayed into his timeline.
She tweeted last June, "I just want to say I’m proud to be British, proud of our history, of the Queen, our democracy and the opportunities given to people from every background. How many immigrants are Members of Parliament in other European countries? Not very many. This is the country of opportunity".
"What an utterly imbecilic tweet" replied Flannery QC. "You really need to step outside of your Beaconsfield bubble woman."
From flâneur to furious.
Litigation clients may pay Mishcon good money for pointed prose, but it is a sensitive time for the firm as it seeks to present a squeaky clean image in readiness for a planned IPO.
Even though Flannery's tweets lend support to the firm's tagline, "It's business. But it's personal", some of his more intemperate zingers have been erased, and the firm told RollOnFriday he was sorry.
"Mr Flannery recognises and regrets that his tweets have caused offence and apologises to those that have been affected", said Mishcon.
