HMRC are written to all the VAT-registered businesses which trade with the EU only as their main source of trade.
The letter sets out what actions any business needs to take now in order to prepare for the unlikely event of the United Kingdom leaving the European Union without a deal.
You can read the letter here. For any business who wishes to stay up to date with HMRC's EU Exit update service you can join by visiting www.gov.uk/hmrc/business-support selecting the 'business help and education emails' section then adding your email address and choosing the 'EU Exit' option.
As ever if you have any specifics you would like me to raise with HMRC as your constituency MP, please do get in touch.
