Blue chip shares struggled for direction for the second day in a row as traders hold their breath over whether US President Trump can deliver his sweeping political programme.
US lawmakers debate Trump's bill to repeal Obamacare health reforms on Thursday (23 March), with the vote expected to hang on a knife edge. Investors will take the result as a sign of the President's chances of delivering the deep tax cuts and a $1trn infrastructure programme he campaigned on.
The FTSE 100 Index slipped seven points to 7317.8, with German's DAX and the Cac 40 in France both slightly higher.
In London, Next was the strongest riser in the top flight, even though it posted its first fall in profit for eight years as the high street fashion chain was hit by tightening household budgets, weaker sterling and poor stock selection.
The retail bellwether posted a 3.8% slide in annual pre-tax profits to £790.2m, down from £821.3m last year, the first time it has failed to grow profits since its 2008-09 year, at the height of the financial crisis.
The chain said full-price sales slipped 1.3%, as the business neglected to stock some of its best-selling staples. But it said it has beefed up its range of staples, which will be reflected in its summer stock, but it added "we will not have our ranges where we want them until the autumn season".
Neil Wilson, senior market analyst at ETX Capital, said: "Next has to get its house in order and focus more on its core product – something it says it began doing in January.
"Fundamentally the business remains strongly cash generative even if it's not expanding rapidly and is able to maintain solid returns to investors."
Next lifted more than 7%, or 282p to 4167p.
