London (CNN Business) 1. Brexit vote: The British pound could be volatile Tuesday ahead of a crucial vote on Brexit.

UK lawmakers are widely expected to reject the divorce deal with the European Union negotiated by Prime Minister Theresa May. The only real question is the margin of the loss.

Analysts have warned that the pound is likely to weaken following the vote. The currency was trading slightly lower on Tuesday in London at $1.28.

Yet there is a "silver lining" for the pound, according to Societe Generale strategist Kit Juckes. A defeat for May increases the chances that Brexit will eventually be delayed, or called off altogether.

"There's a case for hiding way from all things UK and all things Brexit, but there's still more upside for sterling than downside from here," Juckes said in a research note.
