At 4pm today, a march organised by the Scottish Young European Movement will take place in Edinburgh.

Liberal Democrats will be there – I’m picking up the placards and leaflets to hand out in a while. You can tell how much I love this cause as I’m having to give up watching both the British Grand Prix at Silverstone AND Andy Murray in the final at Wimbledon to go.

We are meeting at the Floral Clock at the entrance to Princes Street Gardens near the National Gallery of Scotland at 3:30 – and for those who want to watch at least some of the tennis, some of us are heading to the Haymarket pub from 1:45 to cheer Andy on for an hour or so.

Speakers at the rally include John Edward, who ran the Scotland Stronger in Europe campaign and our new MSP for Edinburgh Western Alex Cole-Hamilton.

We know that Alex can deliver a cracker of a speech on the subject – his debut speech to Parliament was in the EU debate.

It is a measure of the success of the European project that I am only the second generation in the recorded history of my entire family to never have to contemplate taking up arms against our nearest European neighbours. It is a comfort that I would extend to my three children, Finn, Kit and Darcy, and to theirs to come. It is from the shared desire for a continued and lasting peace that the originating treaties of the European Union emerged. First, there was the European Coal and Steel Community in 1951, so that no country could ever again build a war machine, and then there was the treaty of Rome, which led to a single market in which the free movement of goods, people, capital and services has come to represent the most important charter for freedom that the world has ever seen. It is a solidarity of nations that has become a family.

The Brexiteers such as Margaret Mitchell and her colleagues paint a very nice picture of what it would be to reclaim all our sovereignty, but it is a doctrine of isolationism, pure and simple. I put it to you, Presiding Officer, that in this increasingly globalised world, human traffickers will never recognise that isolation. Climate change will not recognise it, and neither will terrorists. If we were to leave, we would be a tiny archipelago of islands adrift in a sea of economic uncertainty. That is why those on the Liberal Democrat benches are so proudly and full-throatedly backing the remain campaign.

If you’re in or near Edinburgh, do come and join us.
