The FTSE 100 <.FTSE> gained 0.1 percent, with household goods and food sectors boosting the index while miners weighed.

Reckitt Benckiser led gainers after saying it would sell its food business to U.S. spice and herbs company McCormick & Co Inc for $4.2 billion.

"By 2020, RB should be one of the fastest growing names in (the) global staples (sector), with superior returns and cash generation, in our view," said Morgan Stanley analysts.

Royal Mail (>> Royal Mail) gave back some of yesterday's strong gains, falling to the bottom of the blue-chip list, down 2.4 percent.

EasyJet (>> EasyJet) and British Airways owner IAG (>> International Consolidated Airlines Group) were among top blue-chip losers, down 1.7 to 2.2 percent.
