UK stocks headed higher on Friday, boosted by a weaker pound, which slid further on growing speculation that the government will call a snap election, MarketWatch reports.

The FTSE 100 index rose 0.1% to 7,517.55, rising for a seventh session in the past eight. For the week, the London benchmark was on track for a 1.9% gain, which would be its biggest weekly advance since early August.
