LONDON, Nov 28 (Reuters) - The dollar was stuck near a two-month low on Tuesday as traders waited for the confirmation hearing of new Federal Reserve chair Jerome Powell, while the pound slipped from a two-month high as Brexit-related doubts began to re-exert their grip.
European shares rose, supported by consumer staples as Anglo-Dutch Unilever said it favoured a single base, and by oil and gas stocks after Royal Dutch Shell cancelled an austerity dividend.
Powell, seen as a continuity choice at the Fed, defended the U.S. central bank's use of broad crisis-fighting powers and signalled a willingness to move aggressively against a downturn, in remarks prepared ahead of the 1500 GMT hearing.
"The market sees Powell as mister continuity ... but I think there is some risk around the event," said Saxo Bank's chief FX strategist John Hardy. "There are lots of hypothetical questions they could ask him ... and if he appears on the hawkish side there could be some volatility."
The dollar rose 0.2 percent against a basket of six major currencies.
