"The whole issue [of Scotland’s future within the EU] is precarious because Scotland is not a state, Scotland is part of the UK. My own judgment is that the SNP will settle for something less than full EU membership because we can’t get membership until all 27 members agree, and that takes time," Wilson said.
Although 62 percent of Scottish voters backed continued UK membership of the European Union at Thursday's referendum, 52 percent of all UK voters opted for Brexit.
Earlier in the day, the leaders of France and Spain expressed their opposition during informal talks with the SNP over potential Scottish membership of the bloc in the future as the current SNP leader, Nicola Sturgeon, held a series of talks with senior officials in Brussels.
According to Wilson, who has launched a new strategic paper detailing how Scottish secession from the United Kingdom could be achieved, the British government is too weak to refuse Scotland's request to hold a second referendum.
"So you get to the stage where political aspects are dealt with and I think, given London is in a very weak situation at the moment, they would be forced to offer a second Scottish independence referendum," Wilson added, warning independence supporters against rushing to secure such a referendum.
Scottish voters took part in an independence referendum in September 2014 that saw 55 percent of voters backing Scotland’s continued membership of the United Kingdom which was established in 1707.
