Sorry to hear this.
What would you like to know about this please?
Unfortunately, other than lodging a complaint, there is not much legally you can do as there is no evidence that Royal Mail was negligent and under what circumstances someone else signed for your letter.
You may complain to the police about it if you wish to as interference with mail is an offence under the Postal Services Act 2000. It could also amount to theft under the Theft Act.
All the best, ***** ***** a positive rating if this is helpful.
