"Markets (are) tentatively higher ... following gains in the US as the Federal Reserve pledged to keep interest rates near zero for what they term a considerable time," said Andy McLevey, head of dealing at broker Interactive Investor.
"Any gains are likely to be muted though as the people of Scotland go to the polls to determine whether they go it alone and vote for independence or remain part of the UK.
"Until the results are known early tomorrow morning many investors will be sitting on the sidelines."

After a closely watched meeting, the Fed said it would stick to its steady-as-she-goes policy, keeping borrowing costs at a record low of 0-0.25 percent despite growing calls for a rise as the economy strengthens.

Results are not expected until early on Friday morning.
