The youngest member of the Scottish Parliament and new Green MSP Ross Greer starts his maiden speech.

Twenty-one-year-old Mr Greer become the youngest ever MSP after being elected for the Scottish Green Party for West of Scotland region.

He was just 15 when he joined the party and has also served as a member of the Scottish Youth Parliament.

Mr Greer says this referendum will have a profound impact on Scotland and at UK level the debate has been an internal debate by the Tories.

He says the EU has brought huge benefit to our environment.

The Green MSP says European cooperation has brought us decades of peace. 

Labour MSP Daniel Johnson takes to his feet to make his maiden speech in Holyrood.

Mr Johnson says his constituency Edinburgh Southern polls as one of the most pro-EU areas in the UK.

He says Europe matters to his constituency and remaining in the EU.

"This Johnson is definitely more Alan than Boris."

Boris you all know, but a wee reminder Labour's Alan Johnson is his party's pro-EU campaign leader.

SNP MSP Christina McKelvie says the EU has created great things including workers rights.

Labour MSP Neil Findlay tries to intervene but is refused by Ms McKelvie who says "rudeness doesn't get you anything".

Ms McKelvie goes on to say the EU has helped with equal pay and enshrined human rights.

In his first speech Scottish Conservative Adam Tomkins says he will be voting to remain in the EU but not with the same passion as he had voting against Scottish independence.

Mr Tomkins says the EU is broken but the Leave campaign have been unable to provide any clear reason as to why the UK would be better off not in it. 

The former fisheries minister says the UK could currently make a better deal for fishermen but has not and he does not believe Brexit will improve things.

Fishermen in the north east of Scotland have launched their campaign for the UK to leave the European Union.

The Fishing for Leave group said the Common Fisheries Policy has been a "disaster" for the industry.

However, others in the sector have warned that rushing to exit could "knock the industry back 10 years" and throw it into "crisis".

SNP MSP Richard Lochhead, the former fisheries minister, says this is one of the biggest decisions in Scotland's future.

Mr Lochhead says he strongly believes Europe's nations must work together and share sovereignty.

He says he is saddened by the referendum debate being dominated by immigration.

The SNP MSP says Boris Johnson wants to leave but he should knuckle down and help those in need.

What's happening? What's a referendum? What's the EU? Why are we having a referendum? Who can vote? How do you vote?

So many questions and the BBC provide answers to these and many, many more questions here.

The Scottish Labour leader says we cooperate across an entire continent.

Ms Dugdale says human rights, free speech and democracy are now taken for granted.

She says we are richer for having been in the EU.

The Labour MSP says there is no such thing as a guaranteed win and this is too important for half-hearted support and she will argue for Remain with all she has got.

Ms Dugdale says "We are more secure in bigger alliances than standing alone."

Ms Dugdale says we will hear from her colleague Elaine Smith on the socialist argument for leaving but her party will campaign to remain.

The Scottish Labour leader says Remain must argue and reach the head but also reach the heart.

She says she will argue the case for workers rights that are protected by the EU.

Scottish Labour leader Kezia Dugdale says all of Europe's eyes are currently on us.

Will we turn our back on our neighbours or face the world together, she asks.

Mr Carlaw says he want to be an internationalist and not an isolationist and therefore the right vote is one to vote remain. 

Mr Carlaw says he thought the independence referendum engaged both the head and the heart but he now finds himself caring more than he thought he would about the EU referendum outcome.

The Tory MSP says he is astonished Nicola Sturgeon will star in a Sci-Fi radio play in which she plays herself: The Kraken Wakes

He says Ms Sturgeon says this represents a material change in circumstances, to much laughter.

Mr Carlaw says there is not any great interference from Europe in our sovereignty.

Mr Carlaw details the historical reasons for backing remaining in the EU.

The Tory MSP says the argument that the EU has acted as a break on our prosperity is an "absolute nonsense".

Scottish Conservative MSP Jackson Carlaw says the leaders of all the political parties are in favour of Remain, as he is, and this is his personal position he is debating today.

Mr Carlaw asks if people are sufficiently engaged in the EU debate.

He says this is a fundamentally important decision.
