Boris Johnson’s statement announcing he will quit the Commons is not brief – more than 1,000 words – and, as ever with the former prime minister’s pronouncements, there is a lot of often barely hidden subtext: I have received a letter from the privileges committee making it clear – much to my amazement – that they are determined to use the proceedings against me to drive me out of parliament. They have still not produced a shred of evidence that I knowingly or recklessly misled the Commons. This is Johnson trying to preshape opinion about the privileges committee report into whether he lied to MPs about lockdown-breaking parties, which he has seen but is not yet public. This is the statement’s key message: whatever the evidence, Johnson and his allies will always insist he was wronged. They know perfectly well that when I spoke in the Commons I was saying what I believed sincerely to be true and what I had been briefed to say, like any other minister. They know that I corrected the record as soon as possible; and they know that I and every other senior official and minister – including the current prime minister and then occupant of the same building, Rishi Sunak – believed that we were working lawfully together. I have been an MP since 2001. I take my responsibilities seriously. I did not lie, and I believe that in their hearts the committee know it. But they have wilfully chosen to ignore the truth because from the outset their purpose has not been to discover the truth, or genuinely to understand what was in my mind when I spoke in the Commons. Their purpose from the beginning has been to find me guilty, regardless of the facts. This is the very definition of a kangaroo court. This is the other central message to not just this statement but most of Johnson’s public output since he was ousted – the idea that not only has he done no wrong, but that there is a conspiracy to remove him from politics. Both the argument and the seeming lack of any real evidence to back it up are strongly reminiscent of Donald Trump – a repeated theme in this missive. Most members of the committee – especially the chair – had already expressed deeply prejudicial remarks about my guilt before they had even seen the evidence. They should have recused themselves. In retrospect it was naive and trusting of me to think that these proceedings could be remotely useful or fair. But I was determined to believe in the system, and in justice, and to vindicate what I knew to be the truth. A more neutral observer might argue that Johnson in effect had no option but to agree to the privileges report and hope for the best. This was not a choice. It was the same faith in the impartiality of our systems that led me to commission Sue Gray. It is clear that my faith has been misplaced. Of course, it suits the Labour party, the Liberal Democrats, and the SNP to do whatever they can to remove me from parliament. Sadly, as we saw in July last year, there are currently some Tory MPs who share that view. I am not alone in thinking that there is a witch-hunt under way, to take revenge for Brexit and ultimately to reverse the 2016 referendum result. The use of “witch-hunt” is a presumably deliberate echo of Trump, whose paranoid, conspiratorial tone infects Johnson’s words throughout. He also explicitly amplifies another common and similarly evidence-lacking claim of his more vehement supporters – that removing him is part of a wider plot to reverse Brexit. My removal is the necessary first step, and I believe there has been a concerted attempt to bring it about. I am afraid I no longer believe that it is any coincidence that Sue Gray – who investigated gatherings in No 10 – is now the chief of staff designate of the Labour leader. Nor do I believe that it is any coincidence that her supposedly impartial chief counsel, Daniel Stilitz KC, turned out to be a strong Labour supporter who repeatedly tweeted personal attacks on me and the government. More paranoia, more Trump-style personal attacks. On Gray, it is worth remembering that Johnson welcomed the former senior civil servant’s report into Partygate, one that most observers believe was relatively soft on him. When I left office last year the government was only a handful of points behind in the polls. That gap has now massively widened. Yes and no. In July 2022 a few polls had the Conservatives five or six percentage points behind Labour. Others had the gap at 15 points or more. Johnson’s personal polling was abysmal, what remained of his brand was tarnished not just by Partygate but by the endless other dramas that surrounded his premiership. Just a few years after winning the biggest majority in almost half a century, that majority is now clearly at risk. Our party needs urgently to recapture its sense of momentum and its belief in what this country can do. We need to show how we are making the most of Brexit and we need in the next months to be setting out a pro-growth and pro-investment agenda. We need to cut business and personal taxes – and not just as pre-election gimmicks – rather than endlessly putting them up. We must not be afraid to be a properly Conservative government. Why have we so passively abandoned the prospect of a free trade deal with the US? Why have we junked measures to help people into housing or to scrap EU directives or to promote animal welfare? Some more wishful thinking mixed with fairly dishonest revisionism. Johnson’s policy was not “properly” Conservative in the traditional sense – his 2019 offering was a creative mix of free trade Brexitism and highly interventionist state spending, under the banner of levelling up. And a US trade deal was not “abandoned” by the UK – Washington simply did not want one. We need to deliver on the 2019 manifesto, which was endorsed by 14 million people. We should remember that more than 17 million voted for Brexit. I am now being forced out of parliament by a tiny handful of people, with no evidence to back up their assertions, and without the approval even of Conservative party members let alone the wider electorate. I believe that a dangerous and unsettling precedent is being set. Setting aside yet more claims of a plot, students of recent Conservative party history might agree that it is not ideal how the party has switched leaders four times since 2016 on the say so of just party members, or in the case of Sunak, just Tory MPs. That is how Johnson himself took over from Theresa May – forcing out a prime minister who had won power (however limited in her case) at a very recent election. The Conservative party has the time to recover its mojo and its ambition and to win the next election. I had looked forward to providing enthusiastic support as a backbench MP. Harriet Harman’s committee has set out to make that objective completely untenable. This statement will particularly raise eyebrows inside No 10, given the sense that Johnson had been using most of his time as a backbench MP to either make money with overseas speeches or undermine Sunak. Since being ousted as PM he has voted in the Commons four times. The committee’s report is riddled with inaccuracies and reeks of prejudice but under their absurd and unjust process I have no formal ability to challenge anything they say. The privileges committee is there to protect the privileges of parliament. That is a very important job. They should not be using their powers – which have only been very recently designed – to mount what is plainly a political hit-job on someone they oppose. It is in no one’s interest, however, that the process the committee has launched should continue for a single day further. So I have today written to my association in Uxbridge and South Ruislip to say that I am stepping down forthwith and triggering an immediate byelection. The crux of the letter – he is quitting, and so the privileges committee can stop work. However, the committee has said it still plans to publish the report, and will meet on Monday. I am very sorry to leave my wonderful constituency. It has been a huge honour to serve them, both as mayor and MP. But I am proud that after what is cumulatively a 15-year stint I have helped to deliver among other things a vast new railway in the Elizabeth line and full funding for a wonderful new state of the art hospital for Hillingdon, where enabling works have already begun. I also remain hugely proud of all that we achieved in my time in office as prime minister: getting Brexit done, winning the biggest majority for 40 years and delivering the fastest vaccine rollout of any major European country, as well as leading global support for Ukraine. It is very sad to be leaving parliament – at least for now – but above all I am bewildered and appalled that I can be forced out, anti-democratically, by a committee chaired and managed, by Harriet Harman, with such egregious bias. A final blast of conspiracism, with the added threat that he is leaving parliament “at least for now” – perhaps a reference to rumours that he may seek another, more secure Tory seat. But while politics can change at speed, especially recent Conservative politics, it seems hard to envisage a way in which the party would want him back.
