UK's main indexes rose on Friday as data showing British consumer confidence hit a 15-month high added to the optimism that a deal over the U.S. debt ceiling was imminent.

The blue-chip FTSE 100 rose 0.2% by 7:04 GMT, turning positive for the week.

Industrial metals miners and energy firms added 0.6% and 1.3%, respectively, as commodity prices were boosted by signs that a deal on raising the U.S. debt ceiling could be done as early as Sunday.

Adding to the upbeat mood, a survey showed domestic consumer confidence rose to its highest in 15 months in May as households took a more positive view of the economy and their finances.

Smiths Group Plc rose 1.0% after the industrial group lifted its annual revenue growth forecast for the third time in five months, as demand for its products improved on decarbonisation trends and from airport upgrades.
