The constitutional monarch of 16 of the 53 member states in the Commonwealth of Nations, Queen Elizabeth II has broken her silence over the impending Scottish independence vote.

On Sunday, Queen Elizabeth II overtly told that she hoped that the Scotland populace would think very carefully about the future when voting in plebiscite that could break up the United Kingdom. After coming out of a morning service at a church in Crathie near her Scotland's Balmoral estate, the monarch replied to a well-wisher's remark that they would not comment the poll.

The Times newspaper reported Queen Elizabeth II stating, "I hope people will think very carefully about the future." The British monarch didn't specify a predilection on how the Scottish people should vote, as she judiciously maintains the neutrality in her constitutional obligation.

Queen Elizabeth II's comments may be interpreted as a suggestion that Scottish crowd, which is looking to embrace independence, should be thoughtful about breaking Scotland's long ties to the United Kingdom, which date back over 300 years.

The Buckingham Palace recently gives out a statement indicating Queen Elizabeth II's plans to remain impartial before the vote for independence on Thursday. The palace also told Reuters that the vote is totally neutral and strengthens the point that is a matter for Scotland's people.

The monarch was repelling calls from some Conservative Party lawmakers that should make her views known before the historic vote that could lead to a potential disintegration of the United Kingdom.

Several independence supporters paraded the streets of Glasgow, Scotland's largest city, on Sunday as referendums showed the rival camps running desperately close. Separatist and unionist leaders worked across the country to entice the four million undecided Scots as well as English and foreign residents form the Highlands and Islands to Glasgow's tenacious inner-city estates that are qualified to vote.

Scottish Independence supporters express that it is time for Scotland to decide on its own leaders and rule itself, at liberty of control from London and politicians they say flout their views and needs. However, those who are against for the move of independence say that their nation is more protected and affluent as part of the United Kingdom and the end of union would shatter three centuries of bonds and shared history as well as bring in pecuniary and fiscal hardship.

Scotland is close to Queen Elizabeth II's heart because of her Scottish mother and she spent most of her childhood there. Her late sister Margaret was also born in Scotland. Meanwhile, nationalists say the 88-year old queen would remain the Queen of Scotland although they give no assurance of the monarch's lasting future.

Queen Elizabeth said through an official statement on Scotland's vote for independence in May in a message to the General Assembly of the Church of Scotland that in the important year of plebiscite, she prayed that whatever the outcome, people of faith and people of goodwill will work together for the common good of Scotland.

With the nearing of the vote of independence of Scotland, Prime Minister David Cameron is expected to visit Scotland to try to convince voters to reject independence and remain part of the United Kingdom.

When Scotland's votes for independence triumph, in 18 months, it would split from the United Kingdom. But Scottish leaders showed a wish to have Queen Elizabeth II serve as head of state of a sovereign Scotland nation.
