She is going with the “it was all approved” line. Guido very much doubts she told the Fees Office she was going to spend most nights of the year with her family rather than at the “main home” (actually her sister’s spare bedroom).
On the basis of the Trend ruling, where the Tory MP in parallel circumstances had to pay back £90,000 and the precedent established ironically by Mr & Mrs Balls, she has a prima facie case to answer. (The Balls’ argued successfully that in the recess and school holidays they spent the majority of the time away from London at their constitutency home, therefore on the basis that they spend more nights there, that was their main home). The Standards Committee needs to take a hard look into the evidence of where she spent most nights.
UPDATE : Isn’t there a huge conflict of interest here? The best independent source of evidence for where Jacqui spent her nights will be the records of the police protection unit. Who oversees the police?
