It is a competitive field, but Chris Grayling is without doubt the most incompetent minister ever to have held office.
There appears to be no limit to his capacity to squander public money and mess things up.
In the latest example of his ineptitude, he has had to pay £33million to Eurotunnel for giving a ferry contract to a firm with no ships.
This came on the same day that the National Audit Office said that, as Justice Secretary, his part-privatisation of the probation service had cost taxpayers £500million.
His spell at the Ministry of Justice also saw the prisoner tagging scandal, cuts to tribunal fees, the prison book ban and the slashing of legal aid.

As Transport Secretary, he has overseen the bungled railway timetable changes that caused hundreds of trains to be cancelled, the East Coast Main Line fiasco and the decimation of the country’s bus network.
Grayling is not just a national embarrassment – he is an expensive liability.
The only plausible explanation for why he remains in his post is that Theresa May wants a minister who makes her look good by comparison.
