Analysts are predicting underlying pre-tax profits for Sainsbury’s to be about £578m in its full-year results tomorrow, down from £587m last year.

Its the morning after Mayday. Which also marked the exact end of Donald Trumps first 100 days. Not sure how many of us were celebrating that .

GfK's long-running Consumer Confidence Index dropped one point to -7 this month. Four of their five indicators decreased, leaving only the Major Purchase Index going up. That means for some reason we'd be more willing to splash out on large electrical items or expensive furniture.

Theresa May will hold talks with the Prime Minister of Japan later as tensions continue to simmer in nearby North Korea.

A mixed bag for Twitter: The number of people using the social network has risen 14% and the firm's losses narrowed in the first three months of this year.

GlaxoSmithKline has beaten analyst expectations by increasing its sales 19pc in the first quarter under new boss Emma Walmsley. Sales at the pharmaceutical giant hit £7.4bn in the three months to March 31, up from £6.2bn a year previously and higher than the £7.25bn pencilled in by analysts.
