There has been much mocking of this claimed e-mail, as it is such an obvious fake written by parliamentary staff.
First of all the MP forgot to delete one of rent/mortgage. You are paying one or the other.
Secondly spelling out what toiletries are in e-mail to an MP is the second sign it is fake, and an obvious rehash of a talking point memo.
Thirdly it swaps from first to third person and the list of items it may help with is far too long.
Finally the Thank You Labour! is so sycophantic that only a party staffer or activist would have written it.
What shocks me isn’t that Labour MPs are so insecure that they feel the need to tweet fake letters to make themselves feel better. It is that the fake e-mail is so badly done. A third former could do a better fake letter.
