Update: The FTSE 100 has fallen as shares in banks and house builders resumed their slide over the turmoil surrounding the UK's exit from the EU.
The UK blue-chip index fell nine points to 7,029, having closed yesterday only marginally lower on a day of political drama, buoyed by the pound's heavy fall.
The pound lifted from yesterday's lows, up half a cent against the dollar at $1.284.
But stocks exposed to the UK domestic economy, which were hit hard yesterday, continued to slide.
Banks fell to the bottom of the FTSE 100 for a second successive day, with Royal Bank of Scotland (RBS) down 2.7% at 218.2p, Lloyds (LLOY) falling 1.6% to 54.5p and Barclays (BARC) off 1.1% at 164.6p.
On the FTSE 250, CYBG (CYBGC), owner of the Clydesdale and Yorkshire banks and Virgin Money UK, was down 2.9% at 255.4p.
