Johnson is by nature a populist. He rode into power on a wave of anti-EU sentiment and anger and frustration at the failure of Theresa May, his predecessor, to deliver on the EU Referendum result. He saw how a powerful minority in the Conservative Party (the Eurosceptics) managed to undermine her administration. Hence, he has to be careful not to antagonise his own back benchers, who are his only real opposition. There are currently some pretty powerful figures in his own party opposing him on this issue so he will need to act cautiously. As a back stop, any stipulated time limit could always be changed at a later date on the basis of new scientific evidence. They have played that card before."A 'time limit' ... could be imposed...."
Could be, eh?
So ... could be there won't be a time limit, then?
