Organisations across Scotland have "serious concerns" about the impact of Brexit, according to a wide-ranging parliamentary report.

What Scotland Thinks brings together the evidence of more than 150 organisations and individuals submitted to Holyrood's Europe Committee to highlight key issues emerging from the vote to leave the European Union (EU).

Committee convener Joan McAlpine said it was clear a "vast majority" thought Brexit would be bad for Scotland.

The report emphasises the need for a better understanding of the short and long-term impact on the Scottish economy of withdrawal from the EU, highlighting the uncertainty expressed by most sectors.

Ms McAlpine called for both the Scottish and UK governments to work with the committee to address the concerns, adding: "The time for greater clarity is now."

She said: "This report provides an invaluable insight into how Scotland sees Brexit and it is fair to say that the vast majority of the submissions expressed serious concern about its impact.

"Scotland thinks Brexit is bad for business and investment, bad for workers' protection, bad for education and bad for the environment.

"There was considerable concern about leaving the single market and the customs union, and the lack of certainty about what will replace them."

Deputy convener Lewis Macdonald said: "Our report also sets out concerns about two further areas.

"Firstly, how we will be able to increase the number of economically-active people in Scotland if we cannot retain and attract workers from other EU member states.

"Secondly, whether existing EU laws in the areas of environment, employment and social policy will be weakened or more poorly enforced."

Evidence taken by MSPs on justice and home affairs raised questions about the status of EU citizens in Scotland, future co-operation in initiatives such as the European Arrest Warrant and with bodies such as Europol and how the volume of EU law in the UK will be dealt with.

Witnesses in the education sector highlighted concerns over college and university budgets, research funding and future participation in EU exchange programmes such as Erasmus.

On agriculture and fisheries, uncertainty was expressed over issues including the replacement of the Common Agricultural Policy while it was acknowledged there could be potential opportunities for Scotland-specific policies.

Questions were asked about how Scotland and the UK would meet legally-binding climate change emissions targets given a reliance on involvement in EU initiatives to reduce the emission of greenhouse gases.

Other issues raised included the impact on equalities law and human rights and the possibility of further devolution when powers are repatriated from the EU.

The evidence was taken before the Scottish Government set out its proposals for a differentiated settlement for Scotland and before Prime Minister Theresa May's speech revealing her priorities for the Brexit negotiations, including leaving the single market.

Scottish Greens external affairs spokesman Ross Greer said: "This cross-party report, drawn from vast amounts of evidence submitted by everyone from farmers to trade unions to business owners, makes clear that Brexit will be bad for Scotland in just about every way imaginable."
