* FTSE 100 down 0.2 pct
* Miners, banks provide support
* Housebuilders continue to slide (Adds details, closing prices)
LONDON, Nov 19 (Reuters) - UK shares eased slightly on Monday but outperformed Europe as relative calm returned after last week's tumult and Prime Minister Theresa May continued to fight for support for her Brexit deal.
The FTSE 100 fell 0.2 percent, giving up opening gains, but strength in the financial and mining sectors helped the index outperform a 0.7 percent slide in Europe.
"Things are a bit calmer and there's not been anything particularly exciting bearing in mind that end of last week," said Mike van Dulken, head of research at Accendo Markets.
With (Other OTC: WWTH - news) the earnings season drawing to a close, UK investors focused on politics as May vowed to fight on to gather support for her draft European Union divorce deal as dissenters in her own party scrambled to trigger a leadership challenge.
"May might have overcome the issue of no confidence vote and that adds an element of certainty and may mean we're looking at a deal rather than a no deal and businesses like certainty," said van Dulken.
Miners also provided support, adding 0.6 percent.
But the gains were more than offset by a slump in energy shares as the session drew to a close, as several investors remained cautious over the outlook for Brexit.
"Some of the stocks that were brutalised the most haven't really bounced, so there's no big UK relief if you look at what's happening on the FTSE today," said Eric Moore, income fund manager at Miton.
Last week, the sector was one of the hardest hit by the chaos over Brexit with investors worrying about the impact of a possible second referendum, general election or hard Brexit on the British economy.
