(Sharecast News) - London stocks were set to edge up at the open on Thursday as Brits headed to the polls amid expectations the Labour party will be voted into power for the first time in 14 years.

The FTSE 100 was called to open around 15 points higher.

Ipek Ozkardeskaya, senior analyst at Swissquote Bank, said: "Labour is walking into this election with more than 20 points advance over the Tories - even the most Conservative parts of the country seem tired of a 14-year Tory rule.

"The two most likely scenarios are a good Labour majority with 150 seats - which is almost double Boris Johnson's 80-seat majority in 2019 - or a supermajority. Both will give the Labour a very large margin to pass whatever reforms they want to pass in the coming years. Normally, investors prefer Conservatives as they have a better grip on spending and debt levels. But this time, even investors want to see Labour take over the reins. For Wall Street, a Labour win is positive for both the UK stocks and sterling.

"Small and medium-sized British stocks will likely benefit more from a Labour win than the FTSE 100 - which is mostly exposed to the global market conditions. Cable rallied to 1.2772 yesterday and is consolidating gains near 1.2740 at the time of writing. Combined with a soft dollar, we could see the end of the Tory rule support the pound and back a move toward 1.30."
