A survey by Norstat found that 51 per cent of Scottish voters do not trust Ms Sturgeon, with just under one-third (32 per cent) having trust in the former SNP leader.
Her net trust rating of -19 represents a huge drop from when she led Scotland’s response to the Covid pandemic and enjoyed a peak score of +18 on trustworthiness in February 2021.
It comes after a series of scandals have tarnished Ms Sturgeon’s reputation since she quit as first minister last year.
The 53-year-old, who continues to serve in the Scottish Parliament as MSP for Glasgow Southside, was arrested in June as part of an ongoing police probe into the SNP’s finances.
Ms Sturgeon, who weeks earlier had seen officers conduct a high-profile search of the home she shares with her husband and ex-SNP chief executive Peter Murrell, was released without charge.
This month, Ms Sturgeon was accused of a ‘shameful cover-up’ after the UK’s official inquiry into the Covid crisis was told all her WhatsApp messages from the pandemic have been deleted.
