In his keynote address to the Scottish Liberal Democrat spring conference in Hamilton, party leader Willie Rennie is set to tell delegates the party's mission must be to ensure every individual achieves their potential, as he offers to make common cause with all those who recognise that the Labour and Conservative are "no longer broad churches but narrow sects".
Mr Rennie is expected to say:
"Leaving your party after many years is hard.
It is a risk. I get that.
To those who have taken those first, bold steps I am full of admiration.
To those in Scotland yet to decide, I say why settle for what you know is not right when you could forge something new that is worth fighting for?
Labour and the Conservative Parties are no longer broad churches but narrow sects.
To miss this chance today will fill you with regret tomorrow.
So, come and talk with me.
Let’s work together.
We have a responsibility to make it happen.
Look at the challenge that we face.
We know Britain isn’t working as it should.
Everyone deserves the opportunity to work hard and build a good life for themselves, their family and their community.
Everyone deserves to be paid a fair wage, to afford a home and to be able to use good public services.
But for many, that’s not the reality today.
People are working hard; they’re playing their part; and yet too many are trapped by a lack of opportunity.
They see the powerful evade their responsibility for the last recession.
When people work so hard to stand still it grates to see the bankers and the billionaires get richer;
And then the billionaires cut and run to tax havens.
Our joint mission must be to ensure every individual achieves their potential.
It is to create a fairer society.
So let us seize this chance.
Like minds should work together to demand better."
