European markets set to open in positive territory despite Trump tariff threat

Good morning from London, and welcome to CNBC's live blog covering all the action and business news in European financial markets on Tuesday.

Futures data from IG suggests regional markets will start the week flat to lower, with both London's FTSE 100 and Germany's DAX expected to open 0.2% higher, France's CAC 0.5% lower. Italy's FTSE MIB is seen opening 0.2% higher.

The upbeat mood for European markets comes after a difficult start to the week, after U.S. President Donald Trump announced at the weekend that he would impose a 30% tariff on goods imported from the EU.

The duty is due to take effect on Aug. 1, and the EU is scrambling to reach a trade deal with the U.S. before then. Europe's Stoxx 600 index closed 0.06% lower on Monday, after shaving off losses late in the day to finish at a session high.

Earnings in Europe come from Experian, Ericsson and Barratt Redrow on Tuesday. Data releases include monthly U.K. retail sales data.
