The index of leading UK stocks <.FTSE> fell nearly 0.2 percent, weighed down by financials and by a rising pound, which typically weighs on dollar-earning companies, while the broader FTSE 250 <.FTMC>, which includes IWG, added 0.1 percent.

The FTSE 100 recorded a seventh straight week of gains on Friday, its longest winning streak since June 2015, as investors began to warm to UK equities amid a wave of deals and takeovers.

Morgan Stanley on Monday upgraded its view on British equities, saying the market should benefit from higher commodity prices and an increase in dealmaking activity despite economic uncertainty over Brexit.
