• GBP/USD inched slightly higher on Thursday as upbeat UK manufacturing data gave sterling a minimal boost as traders eyed radically conflicting polls on next week's British elections.
   
• A May survey of purchasing managers in the manufacturing sector beat forecasts of economists, but the pound's reaction was small, temporarily trimming some losses against the dollar.
   
• The Markit/CIPS manufacturing purchasing managers' index (PMI) slipped to 56.7 in May from a three-year high in April. Aside from the previous month's PMI, that was its strongest reading since June 2014.
   
• The pair upside is expected to be limited as strong resistance at 1.2953 should limit upside and bring a decline towards lower levels in the short term.
   
• To the upside, immediate resistance can be seen at 1.2913, a break above this level would expose the cable to next resistance level at 1.2953.
   
• To the downside, immediate support can be seen at 1.2873, a break below at this level will open the door towards next level at 1.2843.
