Brexit uncertainty weighs on the pound. Still, the dollar's retreat may add some traction to the UK currency. The UK and the EU will resume Brexit trade talks this Tuesday.
The main scenario is a move to 1.2820.
An alternative scenario assumes a decline to the 1.2680 support.
If the price overcomes 1.2780, the GBP/USD pair will have a potential to reach 1.2820.
A break below the 1.2730 support can generate weakness towards the 1.2680
