Scottish support for independence has declined widening the lead for the pro-union campaign a new poll has revealed.

It comes just five days before Scotland votes on whether to separate from the rest of the UK.

A Survation poll on behalf of the pro-union Better Together campaign found support for staying in the United Kingdom was at 54%.

Meanwhile, 46% were planning to vote for independence on 18 September once undecideds were excluded.

The poll comes as a boost to the anti-independence campaign after the latest "poll of polls" yesterday, showed the vote remained on a knife-edge, with just 51% support for staying in the UK.

Survation's last poll on Wednesday showed unionists on 53% and separatists on 47%.

The poll released today showed 9% of Scots were still undecided.

Scotland votes this Thursday on whether to end a 307-year-old union with England and break away from the United Kingdom.

While polls had consistently shown strong leads for the No campaign to reject independence, a recent surge in support for Yes has prompted some investors to sell the pound and the shares of Scottish companies over concerns about the economic ramifications of a split.

The Survation poll found that 40% of respondents believed they and their families would be worse off financially in an independent Scotland, with just 27% saying they thought they would be better off.

Both sides of the debate are making their latest push for votes as the final weekend of campaigning takes place.

Yes Scotland said today would be the biggest day of national campaigning ever seen in the country.

in the space of 48 hours, 2.6 million leaflets are being delivered to households.

For the No camp, Labour big-hitters former prime minister Gordon Brown and shadow Scottish secretary Margaret Curran have been addressing voters in the east of the country.

Elsewhere, the Orange Order held a "Proud to be British" rally in Edinburgh today in support of the Union.

The weekend push for support at the ballot box comes after a leading bank warned that the financial and economic arguments against independence.

It claimed they are "overwhelming" and compared a Yes vote to the mistakes which led to the Great Depression.

The chief economist at Deutsche Bank, David Folkerts-Landau, said voters and politicians had failed to grasp the potential severity of the negative consequences of independence.
