Scottish First Minister Nicola Sturgeon has already demanded the Home Office lift visa requirements on those arriving from Ukraine, as she pledged that the Scottish Government “stands ready to help and play our full part in resettlement effort”.
Hundreds gathered in Prince Street Gardens today in a protest against the Russian President Vladimir Putin.

Demonstrators marched from the Russian Consulate in the city to the Scottish Parliament to make clear their opposition to the invasion.
Since Russian troops went into Ukraine early on Thursday, Scotland has seen a number of protests against the military action of President Vladimir Putin’s Russian regime.
Edinburgh West MP Christine Jardine was among those taking part in the protest in the Scottish capital – which is twinned with Ukraine’s capital Kyiv, where some of the fiercest attacks have been.
Ms Jardine said: “All over Europe people are sending the clearest of messages to the Russian government, to Putin, to say this is not acceptable.
“The people of Ukraine deserve better, the people of Kyiv deserve better and here in its twin city of Edinburgh we are sending our message loud and clear.”
Demonstrations against the war also took place in other cities across the UK and in Europe.
Mr Robertson said: “We need to be open-hearted, we need to support the Ukrainian people. This is their hour of need and we need to be there for them.”
He also told BBC Scotland’s The Sunday Show that Russian diplomats in the UK, including ambassador Andrei Kelin, should be expelled.
“The idea that we should have Russian diplomats in the UK supporting the Kremlin lies about the war in Ukraine is intolerable,” he said.
“This is not normal circumstances, this is not a time for normal diplomatic relations.
“The thing Putin understands is power and the thing Putin understands is people acting and reacting to what it is he is doing.
“So, not only should the Russian ambassador be sent back to Russia to explain the UK is not prepared to put up with what is going, but we have Russian diplomats based in Scotland and we have to ask ourselves ‘Why are these people here in support of Putin’s war in Ukraine?’. It is intolerable.
“This is not business-as-usual territory, this is unprecedented. This is the biggest war we have seen in Europe since the Second World War.
“This is a full-scale war and we have to decide whether we are going to do everything we can within our power.”
Britain, the US, Canada and the European Union have already announced that selected Russian banks will be excluded from the Swift global payments system.
They also said they will be imposing “restrictive measures” to prevent the Russian Central Bank from deploying its international reserves in ways that undermine the impact of sanctions.
This action could lead to a “very, very rapid economic deterioration” within Russia, Mr Robertson said.
“That is what President Putin needs to feel, and we need to work with everybody to maximise the pressure on him so that he realises he cannot go on unchecked.”
He went on: “Unfortunately we’re past the stage of deterrence with President Putin.
“What we need to do is make sure we apply maximum pressure on the Russian government so there is a price to pay for continuing with this aggressive military campaign in Ukraine.”
With war in Ukraine likely to force a rise in both food and energy prices, Mr Roberson said people in the UK need to understand “there will be a cost”.
But he added: “War is even more costly, so let’s do what we can to help President Putin understand he cannot go on with this military aggression.
“Our friends in Ukraine need to know we will do everything in our means to help them, in terms of humanitarian aid, military support and in supporting those who are seeking refuge elsewhere in Europe.
“Sanctions need to be tightened this week, governments need to speak to one another, there is always more we can do.”
He also said discussions are under way between the Scottish Government and UK authorities about whether the oil tanker NS Champion – which is owned and operated by Sovcomflot, a company wholly owned by the Russian government – should be allowed to dock in UK waters.
The vessel is expected to arrive at the Flotta oil terminal in Orkney on Tuesday, with Alistair Carmichael, Liberal Democrat MP for the islands, having raised concerns about this with Prime Minister Boris Johnson.
UK authorities “have got a big decision to take whether we’re going to allow Russian-owned or chartered vessels to dock in UK ports”, Mr Robertson said.
“I don’t think it is time for business as usual, and the Scottish Government is in discussions with the UK authorities about this very particular case, but there will be others.
“This is a very good example of an area where we are going to have to act decisively, in my view, because we cannot carry on as if nothing is happening on the far side of Europe.”
