UK's FTSE 100 flat as energy gains counter mining losses amid US-Iran flare-up

Market Overview and Key Movers

July 13 (Reuters) - UK's FTSE 100 ended flat on Monday as a rally in oil prices boosted energy stocks, helping offset losses in financials and mining stocks as investors assessed renewed military exchanges between the U.S. and Iran.

The blue-chip FTSE 100 index ended flat at 10,498.3 points, while the midcap FTSE 250 edged 0.1% higher.

• Oil prices rose over 4%, sending energy stocks up 3%. [O/R]

Homebuilders and Policy Developments

• Homebuilders rose 2% following a media report that Andy Burnham, who is likely to be the next British Prime Minister, is set to review plans to bring back the "Help to Buy" scheme which was designed to help first-time buyers afford properties.
