spicerack- you may be referring to this. Doesn't sound like 170 miles though so maybe he did something else the Guardian has missed.

I think there were questions about him travelling to his family home in Hertfordshire where his family is and from which he now says he is working.
On the subject of his travel between Herefordshire and London, Jenrick told the Daily Mail: “My house in Herefordshire is the place I, my wife and my young children consider to be our family home and my family were there before any restrictions on travel were announced.
“I have been working in London on ministerial duties, putting in place the system to shield the group most vulnerable to coronavirus and organising the response at a local level. Once I was able to work from home it was right that I went home to do so and be with my wife and also help care for my three young children. By staying at home, we protect the NHS and help save lives.
“I will be staying at my family home until government advice changes or if I am needed in person in Westminster before the parliamentary session resumes after the Easter recess"
