UPDATE 1-Sterling falters as PM May puts stripped-down Brexit deal to vote

Sterling slid toward a three-week low as Prime Minister Theresa May prepared a parliamentary vote on a stripped-down version of her twice-defeated Brexit deal. Attorney General Geoffrey Cox said the vote was the last chance to use the legal right to delay Brexit until May 22, otherwise the delay expires April 11.

Traders stayed on the sidelines, thinning liquidity and amplifying swings in the pound.
