The FTSE 100 fell on Monday, led down by mining stocks amid concern about the outlook for the world economy and heading closer to a test of important chart support.
The FTSE 100 <.FTSE> was down 23.62 points, or 0.4 percent, at 5,829.00 by 8:10 a.m., having closed flat on Friday to record a weekly loss of 1.1 percent after two consecutive weeks of gains.

"If we can't hold that then chances are that the rally from the start of June has now finished and that further downside will be most likely.
