The SNP have been tipped to gain five seats at Westminster in a new poll which shows support for Scottish independence is increasing. 

Following days of sleaze allegations being levelled at the Conservatives, a Panelbase survey conducted at the end of the week found that support for the Tories is dropping north of the border. 

It follows a UK-wide poll by Savanta Comres released yesterday which put Labour six points ahead —  a sign that recent revelations about MPs’ second jobs and the handling of the Owen Paterson affair could be hurting Boris Johnson’s party at the ballot box.

The Panelbase poll found support for the SNP at Westminster at 48 per cent  - up one point since September - while support for the Conservatives has slipped two points to 21 per cent. 

Labour is up one at 20 per cent and the Lib Dems are unchanged on 7 per cent.

HeraldScotland:

Sir John Curtice, professor of politics at Strathclyde University, forecast for The Sunday Times, who conducted the poll, that the SNP’s tally of MPs would rise from 48 to 53.

The Tories would lose half their existing six seats, Labour would be stuck on one and the Lib Dems would fall from four to two.

Support for independence has climbed up one point to 49 per cent with opposition at 51 per cent (-1). However, fewer than a quarter (23 per cent) of those asked now believe independence is likely within the next five years — a fall of three points.

The poll of 1,781 voters in Scotland was held between November 9 and 12. The next Holyrood election is not until 2026 but at this stage the SNP looks to be in a commanding position.

On the constituency vote it is polling at 47 per cent (+1), with the Conservatives on 20 per cent (-2), Labour on 19 per cent (+1), Lib Dems on 8 per cent (+1) and the Greens unchanged on 4 per cent.

In the regional vote, the SNP is on 41 per cent (+3), the Tories on 21 per cent (-2), Labour unchanged on 18 per cent, Lib Dems unchanged on 8 per cent, the Greens on 10 per cent (+1) and others at 3 per cent (-1).

On that basis the SNP would remain one seat short of a majority on 64 seats, with the Greens on ten (+2), giving them a combined majority of 19. The Tories would remain in second with 26 seats (-5), with Labour still on 22 seats, and the Lib Dems up from four to seven seats.
