Dan Hodges told the Evening Standard that Emma could be "experiencing severe delays" in getting more work out of TfL. It appears that this wasn't the best way to announce the news about Emma and now he's been put on "gardening leave".
Emma Clarke herself feels sorry for him and said to Metro "Ye Gods, that's awful. I think he misjudged it. I was quite surprised that in their statement they had chosen to draw attention to arguably a negative to their service. Poor Dan."
Personally I wouldn't feel too sorry for him as it appears that he's now in line for a nice pay off, even though he'd only been in the role for a few months and is on a six figure salary.
