Sterling likes it - Boris Johnson most certainly does not.
The pound rose for a second day on Friday (August 16).
As an opposition move to oust the current UK prime minister and form a new government gathered momentum.
If it works, it should limit the risk of Britain crashing out of the EU with no transitional deal - as Johnson has threatened it might.
The main opposition Labour Party leader Jeremy Corbyn is spearheading the move.
"We will put a motion of no confidence against this government in order to try and stop no deal. The Prime Minister seems desperate to take Britain out of the European Union 31st of October without a deal. The problems of that are huge on food, medicine, jobs, industry and investment."
The problem for Corbyn: not all other opposition parties are completely on board.
But for now, markets appear ready to give the plan the benefit of the doubt.
Sterling scaled an 11-day high against the euro - up half a percent.
Versus the dollar, it on was track for its biggest weekly gain since June.
A July bounce in retail sales reported this week - and other signs of resilience in the UK economy - were also providing support.
Though Boris Johnson too has had a boost - from Donald Trump.
The U.S. and UK, says the U.S. president, are moving rapidly towards a post-Brexit trade deal.
Adding it would - quote - be 'fantastic and big'.
