Sir.-With regard to postal services, I agree there has been a great improvement in delivery times, and we now receive post around 9am - full marks.

What is worrying is the non-delivery of post. Since April 4 or 5, some letters - and a recent package - have never reached us.

Who should we blame - sorters or postmen? This needs to be dealt with.
