(ShareCast News) - UK shares recovered after a modest dip at the start of the session, with banks again clocking in with the biggest gains as traders digested another flurry of poll results suggesting Thursday's vote will not result in Brexit.As of 12:00 BST the FTSE 100 was trading higher by 0.03% or 1.94 points to 6,205.94.In comments posted to his Twitter account, US academic Nouriel Roubini warned that a decision to leave the UK could stall the British economy and tip it into recession.Nevertheless, with polls showing a small lead for the 'Remain' campaign, sterling rose by 0.28% against the dollar to 1.4736, recovering the levels seen before the date of the 23 June referendum was announced.On Monday evening, a phone poll conducted by ORB on behalf of The Daily Telegraph revealed that 53% of respondents backed Remain, with 46% showing their support for 'Leave'. However, including undecided voters then Remain's lead was whittled down to just 49.0% against 47.0%.A poll from YouGov carried out for The Times published on Monday evening put support for Remain at 44.0% and that for Leave at 42.0%.According to Ladbrokes, the chances of a 'Remain' vote had shortened to 2/7, with about 95% of all bets over the previous 24 hours had been placed on voters rejecting Brexit.On the data front, public sector net borrowing (excluding public sector banks) printed at £9.7bn for May (consensus: £9.5bn), less than the £10.1bn seen one year ago.Following an upwards revision to April's tally of £1bn, UK state borrowings over the first two months of the fiscal year were 0.8% higher than a year before, versus a forecast from the Office for Budget Responsibility for a decline of 23.0% over all of fiscal year 2016/17.The Confederation of British Industry's total orders balance improved from -8 in May to -2 in June (consensus: -10.0).That indicated that the downturn in manufacturing had drawn to a close, but it remained difficult to be upbeat about the sector's outlook, analysts at Pantheon Macroeconomics said.Acting as a backdrop, US central bank chief Janet Yellen was due to deliver her semi-annual Monetary Policy Report to Congress at 15:00 BST.In the Federal Reserve's policy meeting last week, US rates were left on hold but Yellen hinted at a concern about the recent slowdown in the pace of jobs growth.Her reticence about the prospects of a rate rise in the next meeting or two was noted by economists as a stark contrast to recent comments that suggested a rate rise was looking ever more appropriate in the coming months.In corporate news, Whitbread served up a slight improvement in sales in the first quarter of the year as its Costa coffee shops bounced back from a slowdown in the preceding few months.Group like-for-like (LFL) sales grew 1.8% as although Costa's sales were up 2.6%, the group's Premier Inn hotel chain saw LFL sales slow further to 2.1% from the rate seen in the fourth quarter.BHP Billiton said it was targeting another $600m in coal production costs by the end of the 2017 financial year.The mining group also increased its forecast for coal output for the current year to 43m tonnes, with plans to lift production to 46m tonnes in 2018."While cost compression has been evident across the industry, we continue to work hard under our new operating model to improve our performance," said BHP Billiton Minerals Australia president Mike Henry."Even in today's difficult environment, all of our operations remain cash positive."Saga said it was on track to achieve its targets for the year ending 31 January 2017 and continues to make good progress against its strategic priorities.Ahead of its annual general meeting at its headquarters in Folkestone, the group, which provides products and services for the over 50s, said it had seen solid trading across the core insurance and travel businesses.Chief executive officer Lance Batchelor said: "We have made a good start to the year across our core trading divisions. We continue to focus on our strategic objectives and remain on track to deliver on the targets we set out at our preliminary results on 19 April 2016."Defence company Chemring's shares were hit as it reported a wider loss for the first half and said it expects its full-year 2016 results to "slightly below" market expectations amid higher costs and a delayed contract. Chemring's compiled consensus of analysts' forecasts was for FY16 underlying operating profit of £48.7m.High-tech components manufacturer Senior led the fallers on the mid-cap index after it issued a pre-close trading update on Tuesday, in which it reiterated that margins in the aerospace division will be lower in the first half of 2016.The FTSE 250 firm said activity in aerospace is anticipated to increase during the period in line with expectations, but margins will be lower as the ramp-up of new production programmes continues.
