Burner phone-style sim cards are being sought by police as part of the SNP fraud investigation.

Officers are also probing the purchase of luxury pens, designer pots and pans and even a fridge freezer, the Sunday Mail can reveal.

First Minister Humza Yousaf has admitted he has seen a list of items on a warrant that police either have seized or want to trace as part of their probe into the whereabouts of £667,000 of donations said to be earmarked for an independence campaign.

A luxury campervan has already been uplifted from the driveway of Nicola Sturgeon’s mother-in-law’s home.

Jewellery also forms part of the investigation which has plunged the party into crisis.

Officers were understood to be looking for information from the sim cards which are commonly used in untraceable phones.

A source with knowledge of the investigation said: “Something police are looking for is sim cards used in unregistered mobile phones.

“They want to know the numbers connected with these cards which could also contain numbers called and text messages.
