M&S has had previous apostrophe problems

The slogan "Mum's dreaming of a quiet Christmas just like the one's she used to know" has a rogue second apostrophe.

This is the second such error to have blighted an M&S pyjama line.

In October, the store withdrew a set of children's pyjamas which had a picture of two giraffes and an extra apostrophe on the words "Baby Giraffe's".

The store has sold thousands of the "Mum's dreaming..." Christmas sleep suits since they were introduced into stores and its online catalogue in the Autumn.

The products are out of stock in many stores.

The error in "one's" - which also makes an appearance on the same slogan on a pack of bibs - was only pointed out on Sunday.

Referring to the latest mistake, the store said it was a "silly mistake" and added perhaps it should send its buyers to grammar lessons in the New Year.
