Rayner’s future in balance as firm used to buy flat in stamp duty row says it did not offer tax advice

Report from prime minister's standards adviser, Laurie Magnus, is due today

The conveyancing firm that Angela Rayner used to complete her purchase of an 800,000 flat on the south coast has said it did not offer her tax advice and completed her stamp duty return based only on information she provided.

Joanna Verrico, the head of a small, family-run firm in Kent, said on Thursday it had not provided any advice to the deputy prime minister on how much stamp duty to pay.
