UK FTSE 100 faced choppy session on Tuesday as data showed Britain's budget deficit widened more than expected in May on lower tax revenue and elevated government spending. Royal Bank of Scotland was among main decliners and gave up 4.4% as technical issues over past few days left millions of lender's clients without access to money. Miners and energy producers modestly recovered from previous slump. Rio Tinto PLC gained 0.7% and BP PLC added 1.0%. At the moment of writing FTSE 100 is almost flat at 5,452.
