European equities slid, with the UK's FTSE 100 Index breaking a record streak, and the British pound weakened amid fresh concerns about the UK's departure from the European Union.
The pound fell to its lowest point against the US dollar since October's flash crash amid concerns about a hard Brexit, the UK losing access to any trade and economic benefits with the EU, a day before the nation's Prime Minister Theresa May is slated to detail plans in a speech.
"Even if the pound recovers somewhat in London, it seems as though the realities of a hard Brexit are still not fully priced in," Sean Callow, senior strategist at Westpac in Sydney, told Bloomberg.
"It is difficult to make the case for the pound to avoid testing, probably breaking, the 'flash crash' lows in coming weeks."
Europe's Stoxx 600 Index ended the day with a 0.8 per cent slide from the previous close. The UK's FTSE 100 Index fell 0.2 per cent, France's CAC 40 Index dropped 0.8 per cent, while Germany's DAX Index declined 0.6 per cent.
