Allegations of misappropriated funds In July 2019, AUOB co-founder, Neil Mackay stepped down after claims of misappropriated bucket cash donations were made by a fellow co-founder Manny Singh (who was also suspended at the time as Operations Director). Mackay resigned later in the month.
Accusations of racism In July 2019, co-founder, Manny Singh was sacked as Operations Director by the National Executive of All Under One Banner, due to an alleged breach of Section 65 of the Civic Government (Scotland) Act 1982 for not sticking to the original route for a protest march and timing of the march despite Glasgow City Council's licensing committee ordering changes. Manny described the ruling by the National Executive as a Kangaroo Court. In August 2020, he described the movement was being damaged by anti-English racists who 'joked about colour of his skin'. A spokesperson for AUOB said “All Under One Banner acts in support of Scotland becoming an independent country and does so without any prejudice, be that in respect of race, religion, gender, age, sexual orientation, disability, nationality or ethnicity. The allegations are untrue.”
Planned marches during the COVID-19 pandemic In October 2020, AUOB were criticised for planning to hold a march in Dundee during the
COVID-19 pandemic by
First Minister of Scotland Nicola Sturgeon and Dundee City Council leader John Alexander. The rally was eventually called off.
Inclusion of controversial nationalist groups All Under One Banner has faced criticism for including the fringe ultranationalist group
Siol nan Gaidheal in its marches, which has been described as an
ultranationalist(self-description; disputed meaning) organisation. In 2018, the online magazine
Bella Caledonia criticised AUOB for platforming what it described as a "fascist" group. AUOB replied that while Siol nan Gaidheal's banner was not welcome, it was unable to physically ban the organisation from its marches. SnG went on to say on their website in response to AUOB's requests; "We're quite happy to limit its (SnG flag) use to political rallies in future". In 2022, SNP MSP
Evelyn Tweed apologised for appearing alongside a Siol nan Gaidheal banner at an AUOB march commemorating the
Battle of Bannockburn.
Death of Alistair Darling In November 2023, in reaction to the death of
Alistair Darling, who led the
Better Together campaign opposed to Scottish independence, the official AUOB Twitter account tweeted; "The darling lapdog of London rule who fronted the 2014 campaign to keep the people of Scotland in poverty. Good riddance to this treacherous man." The tweet was deleted following intense criticism. A
Scottish Labour spokesman said: "This is a disgusting tweet from an organisation which has regularly hosted senior SNP figures at its marches. Not only should All Under One Banner delete and apologise for this vile message but the SNP should sever ties with these ghouls permanently." ==AUOB Cymru==
