SYDNEY, March 13 (Reuters) - Asian share markets got off to a subdued start on Wednesday after a mixed finish on Wall Street, while a frazzled pound awaited its fate ahead of yet another make-or-break parliamentary vote on Brexit.
MSCI's broadest index of Asia-Pacific shares outside Japan .MIAPJ0000PUS eased 0.1 percent in slow trade. Japan's Nikkei .N225 dipped 0.3 percent and Australia's main index .AXJO slipped 0.4 percent.
E-Mini futures for the S&P 500 ESc1 were off 0.08 percent.
Risk appetite had been dampened after British lawmakers crushed Prime Minister Theresa May's European Union divorce deal, forcing parliament to decide within days whether to back a no-deal Brexit or seek a last-minute delay. voted against May's amended Brexit deal by 391 to 242 as her last-minute talks with EU chiefs on Monday to assuage her critics' concerns ultimately proved fruitless.
Parliament will vote later Wednesday on whether to leave the EU with no deal, and if that fails, a further vote on Thursday will decide whether to extend the Brexit deadline.
"The vote today seems certain to go against the government as well," said David de Garis, a director of economics and market at National Australia Bank.
"Assuming the Thursday vote finds a majority in favour of an extension - as we expect - it will likely be of some comfort to sterling," he added. "It's still a fast moving environment, with political pressure at understandably extreme levels."
The pound could do with some comfort after a wild couple of sessions. It was last at $1.3063 GBP= , having been as high as $1.3296 and as low as $1.3017 so far this week.

On Wall Street, Boeing Co BA.N shed another 6.1 percent for its biggest two-day drop since June 2009, as more countries grounded the company's best-selling 737 MAX planes following Sunday's crash in Ethiopia, the second fatal crash in months.
