In theory a new executive can't be formed unless both SF nominate a first minister, and the DUP nominate a deputy first minister - as both are supposed to do as the largest parties in the nationalist and unionist camps. That is why the positions are actually co-equal, one can't do anything without the other.

The DUP have said they will refuse to do so until the "protocol is sorted out". They have oscillated between saying it has to be got rid of entirely, and saying it has to be reformed, but have never been specific as to what reforms would satisfy them.

They will come under a lot of pressure to form an executive as the vast majority of voters want the Executive to be formed and to function effectively. So they risk losing more support by holding all of N. Ireland to ransom over an issue which is actually a matter between the EU and UK.

If they don't form an executive within 6 months new elections may be called which could be very damaging for them. However if the EU make concessions too quickly the run the risk of being rejected outright.

So a expect a slow war of attrition, with the DUP expecting Boris to act unilaterally to dig them out of a hole of their own making. Who knows what Boris will do?
