(Reuters) - Financials and mining stocks supported the British blue-chip index on Wednesday as investors awaited indicative votes on a series of alternate Brexit options in parliament, while midcap Bellway's upbeat first-half boosted housebuilders.
The FTSE 100 edged 0.1 percent higher and the FTSE 250, which is more domestically focused, was up by 0.6 percent at 0940 GMT.
Barclays (LON:BARC), Royal Bank of Scotland (LON:RBS) and Lloyds (LON:LLOY) were all higher with CMC Markets analyst Michael Hewson attributing gains to hopes that lawmakers could agree a possible next course of action which could lead to a softer Brexit.
That, and strong half-year results from midcap homebuilder Bellway (LON:BWY), sparked gains in housebuilders, which are considered to be particularly Brexit-sensitive.
Persimmon (LON:PSN), Barratt and Taylor Wimpey (LON:TW) were among the biggest risers on the main bourse.
Prime Minister Theresa May is also set to address her Conservative lawmakers, possibly to set out a timetable for her departure to win parliamentary support for her controversial Brexit deal after being heavily defeated twice in parliament.

Struggling department store chain Debenhams surged more than 50 percent to 3.7 pence, below the 5 pence a share possible buyout offer from Mike Ashley's Sports Direct (LON:SPD). Sports Direct gained nearly 3 percent.
"Mike Ashley has clearly decided it’s double rather than quits on Debenhams. The potential 5p offer would be a generous one for shareholders, but it comes with strings attached for Debenhams, in particular appointing Mike Ashley as CEO," Laith Khalaf, Hargreaves Lansdown (LON:HRGV) analyst, said.
