Boris's message: if I can run London, I can run Britain

The Mayor cleverly presented his record of governing London as an audition for one day running the country.

Boris Johnson didn’t need to be disloyal to David Cameron in his speech to the Conservative conference today and he wasn’t. He was merely very discourteous. Picking up reports that the Prime Minister had referred to him as a “blonde mop” he repaid the compliment in vigorous back-handed style. Cameron, he said, is a “broom” sweeping up Labour’s mess. George Osborne, he added, is a dustpan.

Johnson knows Cameron well enough to understand that nothing gets under his skin quite like lèse majesté. The informality, picking the Prime Minister out of the crowd, calling him “Dave” and wishing him a happy birthday with a wilful lack of deference will have been exquisitely irritating. The  over-chummy manner of delivery contained a deadly whiff of ridicule. The Mayor of London didn’t attack the Prime Minister on policy but nonetheless found a way to diminish his stature. 

That served the underlying purpose of Johnson’s speech which was to present himself not necessarily as a current rival to Cameron but as his equal nonetheless. The bulk of Boris’s speech was a celebration of his record in running London with an emphasis on economic vibrancy. He talked about creating a “platform for growth” – developing young people’s skills, finding them jobs, developing infrastructure, boosting exports and attracting investment. It was optimistic in tone and ambitious in scope, yet cleverly contained in the Mayor’s own geographical remit.

There can be little doubt what the objective was here. Boris is setting up his record of governing London as an audition for one day running the country. He was rehearsing a celebration of what can be achieved in the capital – both in terms of beating Labour and kick-starting the economy – as a blueprint for how Conservatives should feel more confident about what they can achieve as a national party. (Whether or not his record will ever justify such exuberance is an entirely different matter.)

He said nothing that sounded like an explicit threat to Downing Street and the Prime Minister’s aides affect to be pointedly relaxed about Boris’s ambitions. The Number 10 line is that Johnson will obviously serve his full term as Mayor, by which time the next election will already be decided. If he wants to do something after that – enter parliament or aspire to be leader – it is a matter for future conjecture that is, in political terms, so distant as to be unworthy of further comment.

Privately, Number 10 sources argue that if Cameron wins the next election, he stays on as leader. If he doesn’t he will almost certainly step down and then Boris might or might not engineer a way to make himself a candidate for the succession. Either way, a straight Boris v Dave contest will never happen. Ergo, Johnson is not a threat to Cameron.

It is a plausible argument but one that ignores the slow drip effect on party morale and Prime Ministerial authority of having, in the wings and periodically intruding on stage, an ebullient, popular Tory figurehead who pointedly refuses to genuflect before the leader. At the moment, Downing Street’s approach is to ignore Boris and laugh along through gritted teeth. Before long, Cameron will surely feel the need to find a more active strategy for cutting the London Mayor down to size.

The problems with ending encryption to fight terrorism

Forcing tech firms to create a "backdoor" to access messages would be a gift to cyber-hackers.

The UK has endured its worst terrorist atrocity since 7 July 2005 and the threat level has been raised to "critical" for the first time in a decade. Though election campaigning has been suspended, the debate over potential new powers has already begun.

Today's Sun reports that the Conservatives will seek to force technology companies to hand over encrypted messages to the police and security services. The new Technical Capability Notices were proposed by Amber Rudd following the Westminster terrorist attack and a month-long consultation closed last week. A Tory minister told the Sun: "We will do this as soon as we can after the election, as long as we get back in. The level of threat clearly proves there is no more time to waste now. The social media companies have been laughing in our faces for too long."

Put that way, the plan sounds reasonable (orders would be approved by the home secretary and a senior judge). But there are irrefutable problems. Encryption means tech firms such as WhatsApp and Apple can't simply "hand over" suspect messages - they can't access them at all. The technology is designed precisely so that conversations are genuinely private (unless a suspect's device is obtained or hacked into). Were companies to create an encryption "backdoor", as the government proposes, they would also create new opportunities for criminals and cyberhackers (as in the case of the recent NHS attack).

Ian Levy, the technical director of the National Cyber Security, told the New Statesman's Will Dunn earlier this year: "Nobody in this organisation or our parent organisation will ever ask for a 'back door' in a large-scale encryption system, because it's dumb."

But there is a more profound problem: once created, a technology cannot be uninvented. Should large tech firms end encryption, terrorists will merely turn to other, lesser-known platforms. The only means of barring UK citizens from using the service would be a Chinese-style "great firewall", cutting Britain off from the rest of the internet. In 2015, before entering the cabinet, Brexit Secretary David Davis warned of ending encryption: "Such a move would have had devastating consequences for all financial transactions and online commerce, not to mention the security of all personal data. Its consequences for the City do not bear thinking about."

Labour's manifesto pledged to "provide our security agencies with the resources and the powers they need to protect our country and keep us all safe." But added: "We will also ensure that such powers do not weaken our individual rights or civil liberties". The Liberal Democrats have vowed to "oppose Conservative attempts to undermine encryption."

But with a large Conservative majority inevitable, according to polls, ministers will be confident of winning parliamentary support for the plan. Only a rebellion led by Davis-esque liberals is likely to stop them.
