LONDON, Jan 13 (Reuters) - Britain's blue-chip share indexreached record highs on Friday, extending its historic winningstreak to a 14th straight day of gains.

The index's longest winning run since its inception in 1984has also been notable for the relatively modest daily gains.After touching an all-time record high of 7,338.49 points, itended the session at a record closing level of 7,337.81 points,up 0.6 percent.

"There are people who want to say this is the moment it'sgoing to turn around, but each day they get proven wrong," IGmarket analyst Josh Mahony said.

He added that a likely further devaluation of the pound inthe next months would support the index higher. "But the gainsare not exuberant."

Brokers pushed broadcaster ITV towards the top ofthe FTSE. Goldman Sachs added the stock to its conviction list,saying it is a likely M&A target. The broadcaster was also oneof JPMorgan's top picks in the European media sector.

House-builders also helped the FTSE rally, with houseimprovement company Kingfisher marking its best daily gain sinceSeptember. Barratt Development led sectoral gains.Persimmon and Taylor Wimpey also gained 1.4percent and 0.9 percent respectively.

"If you want to sleep at night, you'd probably buy aPersimmon or Taylor Wimpey. If you want a bit more rock androll, you might buy a Redrow or a Bovis," Jefferiesanalyst Anthony Coding said.

Pharmaceuticals were buoying the index, rebounding afterbeing weighed down on Thursday by U.S. President-elect DonaldTrump's criticism of high drug prices, and after a meeting ofexecutives of companies including Britain's Shire todiscuss caps on price increases.
