• GBP/USD declined on Wednesday, as the pound came under selling pressure as upbeat ISM U.S. services data boosted dollar and  fears of a hard Brexit from the European Union weighted on sterling.
   
• The ongoing weakness is set to continue for this pair as the resistance level at 1.2850 is likely to act as strong barrier to the bulls and bring a further decline towards lower levels.
   
• To the upside, the immediate resistance can be seen at 1.2798 a break above this level would expose the cable to next resistance level at 1.2850.
   
• To the downside, immediate support can be seen at 1.2747, a break below at this level will open the door towards next level at 1.2683.
