LONDON (MarketWatch) -- Shares in supermarket giant Tesco PLC were among the strongest performers on the U.K.'s benchmark index Tuesday after the company posted a strong sales update, with consumer-products company Unilever PLC also rising on the back of a broker upgrade.

The FTSE 100 index rose 0.6% to 5,805.47 as oil companies and construction-related stocks also provided support.

Other European markets were also higher Tuesday, with Irish stocks showing the strongest gains as analysts said the government's budget plan is likely to scrape through a vote in parliament.

Shares in Tesco rose 1.9% in London after the company said sales in the latest quarter rose 8.2%, helped by strong growth for its Asian and U.S. operations.

Jefferies International analyst James Grzinic said the figures were "slightly better than anticipated," helped by a positive impact from foreign-exchange rates and a strong performance from the group's financial-services arm.

Unilever (UL) jumped 3% after Morgan Stanley lifted its rating on the group by two notches to overweight from underweight.

Oil and mining stocks added to the gains, with BP PLC (BP) rising 1.5%. The move came after reports that the firm could sell some North Sea assets and that Pakistan's national oil firm has asked for a deadline on bids for BP's assets in Pakistan to be extended.

Higher metal prices helped lift shares of Lonmin PLC 1.1% and Kazakhmys 2.6%.

Among smaller companies, shares in house builder Bellway PLC rose 5.7% after the company said it expects pretax profit for the fiscal year to rise 20%.

Wolseley , which supplies building materials and plumbing products to contractors, was another climber, adding 3.5% on the benchmark index after saying trading profit in its fiscal first quarter rose 39% as demand improved in most countries.
