The Guardian started asking No 10 about Cummings being sighted in Durham on 5th April and got blanked and subsequently.

On April 23rd his wife publishes an ambiguous article in the Spectator. Based on the fact that the article is not explicit about their actions you have read in the possibility that she was already in Durham. No-one seems to have a problem with you believing it though I am sure you will equally value my opinion that the article is post-event poppy-cock written in the knowledge that their actions were being investigated by the press.
