It is a year today since I became party leader, and a great deal has happened since.

Thanks to the efforts of so many of our members and campaigners, we had the best set of local election results of the three main parties in England in councils gained and the best overall for us in fifteen years. We have every reason to hope that next year will be better still – we are already preparing.

The by-election in Lewisham East was our best against Labour for a decade. Local council contests each week continue to reinforce the positive message our surveys are giving us.

Whatever toxicity attached to the Lib Dem brand after the Coalition has substantially dissipated. Large numbers will vote for us if they think we have a chance of winning and if there is an effective campaign

As well as winning elections, we are setting out big ideas to change the country. A few weeks ago, I detailed an ambitious but realistic approach to house building, describing what could be achieved without the impediment of ideological prejudice.

I have also launched a series of initiatives to confront the issues thrown up by the new digital economy and deal with the ‘data giants’; a group is looking at how best to support lifelong learning for people whose future is potentially subject to the upheavals of technological change; another will soon look more broadly at the impact of new technologies like AI and how best to respond to them.

On the core economy, I have set out a revised approach to fiscal and monetary policy which builds on, but does not destroy, existing structures. We have carried out serious work on land value taxation, which will come before Conference in the Autumn. And I have described how in practice we create a corporate structure which is best described as ‘responsible capitalism’.

On public services, Liberal Democrats continue to lead the argument about the mechanics for funding health and social care with the advice of leading figures in health policy. The Federal Policy Committee has recently set up a new health working group to take forward their work, and to continue our leadership role in mental health policy pioneered by Norman Lamb. Layla Moran, our education spokesperson, has published proposals to address the concerns of parents, teachers and schools, which we endorsed at conference.

The politics of Brexit is moving slowly but substantially in our direction. Where our calls for a final say on the deal for the public were once derided, more and more people are now joining with us in that campaign. A highlight of my year was addressing the 100,000 people amassed in Parliament Square for the People’s Vote march. We remain the leading political force arguing that whatever the parliamentary wranglings over detail, the best course for Britain is to stop Brexit altogether. Giving the people a choice at the end of this dismal negotiating process is the best way to obtain an exit from Brexit

Politics itself is evolving quickly, with movements becoming as important as parties. I see that as an opportunity not a threat. An opportunity for us to grow, and to become the vehicle for millions of voices across the country. I have taken advice from the experts who worked with Justin Trudeau in Canada and Emmanuel Macron in France to see how we can replicate their success

This summer I will be carefully considering that advice and I know that the Federal People Development Committee is already looking at a range of options for party reforms aimed at broadening our tent and building a movement for change. You will be hearing more on these plans in the coming months.

The first year of my leadership has taken place against the backdrop of extreme political volatility. The government is unstable; the principal opposition is not speaking even for its own supporters. A political realignment remains a real prospect during the coming, second year of my leadership – and I’m determined Liberal Democrats should be at the forefront of it
