Scottish voters do not think Nicola Sturgeon has been honest in the Alex Salmond scandal and she must resign if an independent inquiry finds she broke the ministerial code, according to a poll. The Panelbase survey for the Sunday Times found a third of people already think she should quit, but this proportion would surge to 61 per cent if she is found to have broken the code. Ms Sturgeon last week refused to provide any guarantee she would quit, instead telling MSPs "we can debate in this chamber" what her punishment should be. However, only 24 per cent said they would support her staying on. The poll also found only one in three Scots believe she has been entirely honest and recorded a three-point swing from Yes (46 per cent) to No (47 per cent) on independence. Support for independence in Holyrood's constituency vote declined five points since January, although Ms Sturgeon is still just on course to win a majority in May, with 65 seats out of 129. A second, unweighted poll for Scotland on Sunday also indicated that support for separation and public trust in Ms Sturgeon has dropped significantly this year.
