There has been a lot of talk about the party’s future approach to the EU. In a speech to Liberal Democrats in Cambridgeshire this week, Alistair Carmichael MP set out a possible route map back to full EU membership for the UK and has given us permission to reproduce his remarks.

For the last quarter century Britain’s relationship with her European neighbours has never been far from the centre of our political debate.

For the last five years it has been absolutely dominant.

Brexit may now have happened but few would be naïve enough to think that would be the end of the story.

Less than a month after Boris Johnson signed his trade and cooperation deal with the European Union the flaws and gaps are already apparent.

Our fishermen have woken up to the fact that they were used by Johnson, Farage, Gove et al.

Our young people are coming to terms with the loss of the Erasmus Programme and the opportunities that it brought.

Our exporters are finding that before they can take advantage of the tariff-free access of which the Prime Minister is so proud, they must first get past the Tory red tape manufactured in Whitehall on this side of the channel.

Clearly our relationship with Europe will remain with us as a politcal issue for years if not decades to come.

For us as a party that is a challenge and an opportunity.

This is a point where we have to take stock and go back to our liberal first principles – free trade, enterprise, internationalism.

Since Jo Grimond, my predecessor but one as MP for Orkney and Shetland, took up the reins as leader of the Liberal Party we have been consistent in our view that the United Kingdom’s best interests have best been served by being a member of what was then the European Communities or European Union as it is today.

We have not always got it right. Too often our response to an unrelenting barrage of abuse and misinformation by a right-wing press was to be drawn into defending the institutions of the EU and to look, as a consequence, like uncritical fans.

I confess I never found that to be an attractive or even a particularly liberal approach.

That was why in my early years in Parliament I was one of a handful of Lib Dem MPs who wanted to see political reform before we joined the Euro. I think that time has vindicated that judgement.

It was also why I resigned from Nick Clegg’s front bench team in order to vote for the referendum on the Lisbon Treaty that we had promised in our manifesto in 2005.

I remember journalists describing me then as that most unusual animal – the Lib Dem Eurosceptic.

I won’t deny the “most unusual” bit but to the rest my response then, as now, was that as a liberal I would always be sceptical about the workings of government. The need to reform the way we govern ourselves in the UK was one of the main issues that motivated me to join the Liberal Party in 1980 as a fourteen year old schoolboy.

While we have made some progress in decentralising power away from Whitehall in the creation of the Scottish Parliament, Welsh Senned and Northern Ireland Assembly there remains much still to do.

The House of Lords remains stubbornly resistant to reform;

Our electoral system remains obscenely unrepresentative in the governments that it provides;

Local Government has been starved of funds and shorn of power piece by piece for decades.

At no point, however, have my frustrations with the institutions power government and politics dimmed my belief in the fundamental principles that underpin them – respect for democracy and the rule of law.

I mention that now because – as we saw most graphically in Washington DC a few weeks ago – these truths that were once regarded as being so obvious and universally held that it was trite to mention them – are under attack by a movement of nationalist populism as never before.

When the very idea of liberal democracy is under attack then the need for Liberal Democrats is greater than ever.

When historians come to write the story of the first two decades of the twenty-first century that is how I believe (and hope) that the debate about Britain’s relationship with Europe will be seen.

Yes, we have suffered a major set-back in that battle between those who believe that reform is possible and those who will tell you that it will never happen.

Our party has always argued for Scotland to have her own parliament within a federal United Kingdom. Not because of any nationalist sentiment but because we believe that produces better government.

Similarly we have always believed that the United Kingdom, while maintaining its own parliament and institutions should be part of the European Union. There again we should be guided by what produces better outcomes rather than the colours of a flag.

Nothing has changed in that regard. Our Federal Party conference confirmed as much as recently as last September when we passed a motion in these terms “Conference resolves to support a longer terms objective of UK membership of the EU at an appropriate future date to be determined by political circumstances, subject to public assent, market and trade conditions and acceptable negotiated terms.”

That remains the position. The Liberal Democrats are a party that wants to see the U.K. eventually rejoin the EU.

Of course, we should make it equally and emphatically clear that this is not something that we seek immediately. It is probably at best a medium-term objective. Quite apart from healing the divisions that have blighted our politics and communities since 2016 any party in government must be focused on rebuilding our economy post-COVID. Anything else would be unforgiveable.

Even a medium-term objective, however, must demand more than warm words.

This is a time when we as a party need to make it clear that we not only want to see the United Kingdom return to full membership of the European Union but that we have a clear and credible route map for getting there.

Liberal Democrats have always been a party where policy is set by our members, and rightly so. Just as we set ourselves that goal of EU membership at last year’s conference I would like us all to play our part in designing the route map to get us there. Full EU membership may be a medium-term objective but the problems caused by being on the outside are real and acute and immediate.

They need and deserve more than warm words about close cooperation.

So my opening bid in that debate is this.

I would like to see our party argue for the United Kingdom to rejoin the European Free Trade Association and to do so as soon as possible. We were, after all, founding members in 1960.
