British lawmakers were due to vote Tuesday on a plan to leave the European Union following negotiations in Strasbourg over details including Britain's border with the Irish Republic.
Britain is due to pull out of the EU in less than three weeks, on March 29, but Prime Minister Theresa May's government has not been able to win parliamentary approval for its agreement. The impasse has raised fears of a chaotic "no-deal" Brexit that could disrupt businesses in Britain and the 27 remaining EU countries. May said the latest changes should overcome lawmakers' qualms about a mechanism to keep an open border between Britain's Northern Ireland and EU member Ireland.
"Investors will likely favor risk-taking on positive Brexit news and a strong showing on Wall Street overnight," said Nicholas Mapa and Prakash Sakpal of ING in a report. "Technology and energy shares are seen to drive the rally in Asia but market players remain wary ahead of China retail sales data later in the week."
