(Reuters) - British shares wobbled on Monday, as exports data from China missed expectations and rekindled fears of slowing growth in the world's second-largest economy while investors braced for a crucial vote on the country's divorce from the European Union.
London's main bourse <.FTSE>, which makes a lion share of its income abroad, was down 0.4 percent and the more domestically-focussed FTSE 250 <.FTMC> were both down 0.4 percent at 0850 GMT.
The midcaps broke a six-day winning streak a day before a key vote in a divided parliament that is likely to decide the next phase of Brexit proceedings.
The agreement, which May and EU leaders say cannot be renegotiated and is the only one available, will almost certainly be rejected. If so, uncertainty, paralysis and the likelihood of a disorderly 'no deal' Brexit will rise.
In a speech to factory workers in Stoke-on-Trent in central England, Prime Minister Theresa May is expected to say that lawmakers blocking Brexit is now a more likely outcome than Britain leaving the European Union without a deal.
Homebuilders <.FTNMX3720>, among the most exposed to concerns about a cooling economy amid uncertainty over Brexit, hit their highest since late November in early deals as JP Morgan handed the sector a double upgrade to overweight, following an upgrade by BAML last week.
But investors also dumped stocks they deem more exposed to China after data from China showed December exports fell 4.4 percent from a year earlier in its biggest monthly drop in two years.
