The husband of former First Minister Nicola Sturgeon has been arrested in connection with an investigation into SNP finances.

Peter Murrell, the former SNP chief executive, was taken into police custody on Wednesday morning.

Police Scotland said officers were carrying out searches at "a number of addresses as part of the investigation".

Dreghorn-born Ms Sturgeon announced she would step down as First Minister in February after serving more than eight years in the role.

She was replaced by Humza Yousaf last month.

Mr Murrell, 58, resigned as the party's chief executive last month, a post he had held since 1999.

He has been married to Ms Sturgeon since 2010.
