Was Dave Cameron the worst prime minister ever?

Donald Sassoon does not sit on the fence in this scathing review of David Cameron's memoirs: The worst British prime minister ever.

I must admit I have not yet finished the rather long memoirs. I did go the launch event at the Barbican and was rewarded with a 'signed' copy of the book. It looked like a rubber stamp to me.

I think that one of Dave's biggest problems was that he never thought through the consequences of a particular course of action. He could never see more than a couple of moves ahead. On a personal level, I liked him, but one could dismiss that as smooth Etonian charm.

Like most memoirs, it is a rather self-serving book and he doesn't really explain some of his actions. However, 'the worst prime minister ever' is a competitive league, even if one restricted oneself to the period since the First World War. Sir Anthony Eden would surely merit consideration.

Of course, the real charge against Dave from hard core remainers is the Brexit referendum. Dave argues that it would have been inevitable sooner or later and I am inclined to agree.

I voted remain and I regret the decision that was taken. But I have seen enough of the EU close up to be 'sceptical' (in the original meaning of the word) about it as an institution. It's hardly impressive that it allowed a dysfunctional Common Agricultural Policy to absorb so much of its budget. Unlike hard core remainers, I am ready to move on, albeit it with some misgivings.

Why is ministerial turnover so high?

The Institute for Government looks at the high rate of ministerial turnover in the UK which is now as high as for football managers. It cannot be conducive to good government: Keeping ministers in post

Martin Lewis was making the point at Radio 5 at lunchtime that he often found in his discussions with ministers on financial issues affecting consumers that the minister had not mastered their brief and he had to give them a 101 course on what the problem was.

I remember Richard Rose tackling this topic decades ago and pointing out that ministerial turnover was actually lower in countries like Italy that have frequent changes of government.

What does FlyBe tell us about the Johnson government?

British Airways has now submitted a state aids complaint to the EU. I am no expert on the complexities of state aid policy, although in principle one is allowed to boost regional economies. The actual mechanism used by the Government in terms of airport passenger duty may, however, be open to challenge. In political terms the Government would probably welcome a row with the EU that saw it on the side of the regions against Brussels.

The writer on Sanday, Orkney: you can get there by plane, but I used the boat.

The intervention does, of course, raise questions about the Government's commitment to climate change policy. However, those in the south-west and the Scottish highands and islands would argue that the connectivity that Flybe provides is essential to their ability to do business and attract tourists. I must confess that I have a personal interest here as I use Flybe's Birmingham to Aberdeen flights (almost always nearly full) and then connect via Loganair to Grimsetter international airport, Kirwall, Orkney.

The flag of Orkney is based on that of Norway: you can fly direct to Norwegian destinations from Grimsetter.

A Greenpeace spokesman argued on Radio 5 that we should not be supporting unsustainable rural lifestyles. I don't think the growing number of people living in the Orkney Islands, with an economy in which innovation in renewables plays a key part, would see it that way. Island council officials have to fly to the centre of power in Edinburgh: it can't all be done by video links.

However, should one offer a general subsidy to all domestic flights in the UK by adjusting APD? Or should one subsidise particular services that serve a social need, as already happens with Newquay to Heathrow flights by Flybe? The policy objective may be desirable, but there may be more efficient means of achieving it.

Sticking my head above the parapet

I have refrained from commenting about the crisis in the royal family. It seems to me that it is as much of a quagmire as the Labour Party leadership contest. Whatever you say, you will offend someone. When I made a mildly supportive comment about Jess Phillips on Twitter, I got trolled, largely by the hard right, but also the hard left.

It also strikes me that there are so-called 'royal commentators' round every corner, copying their views from each other or promoting their own website, Instagram account or book.

But with the Sandringham Summit today, I could not hold back any longer. Fortunately, two leading constitutional experts from the UCL's Constitution Unit have written a blog post stating that they think the so-called 'halfway house' solution cannot work: It just isn't an option

What is more they are writing a much needed comparative analysis of European monarchies. Remember there are three in the Nordic countries: Denmark, Sweden, Norway. All the Benelux countries have one, although Luxembourg is a grand duchy. However, Luxembourg has the only two monarchs who can claim to be political scientists.

The current King of Spain does have an international relations degree from Georgetown. I had an audience with him when he was crown prince and he seemed very well informed and he asked me good questions. My Spanish handyman is very impressed by the photo of me with him.

Just one more thought. HRH the Prince of Wales intends to slim down the Royal Family if/when he becomes king. This is probably a good idea, but I do feel a bit sorry for the minor members of the royal family who are dismissed as 'hangers on'.

Obvs. I read the Court Circular every day and I am surprised by the number of mind numbing engagements the Queen's cousin, HRH the Duke of Gloucester, has to undertake. One day in the middle of a busy day he 'visited shops in Bridgnorth'. Was this to get a bargain at Poundland or a microwave meal for the evening?

The irony is that he never wanted to be a member of the royal family. He was training to be an architect when his older brother, William, was killed piloting a plane and the Queen told him he had to join the firm. No one ever told me what career I had to follow.
