Boris Johnson's predecessor Theresa May wrestled in vain with the divided parliament that refused to say yes to her negotiated agreement with the EU - but also to one of the alternatives presented.

That led to May's departure and Johnson's advancement, but now he also faces a great opposition from Parliament.

The uncertainty about what happens next is great. Parliament voted on Wednesday for a bill that could force Johnson to postpone Brexit until January 31 next year. But it must be approved by the upper house, where some conservatives have sworn to do their best to prevent it.

Have no constitution

Part of the uncertainty is that the UK does not have a uniform and clearly formulated constitution that clearly defines the rules that apply.

- The rules are not written down so that you can easily follow and know what applies, says James Savage.

- So it always makes it very difficult and it gives Boris Johnson many opportunities to meander through and get into a hard Brexit.

Concerns from the EU

Boris Johnson has criticized May's EU agreement and has said he believes one can negotiate one in his eyes with advantageous one.

What is now taking place in the British Parliament sees the EU as an internal British matter. But attempts to negotiate parts of the agreement that were negotiated with May are already worrying, says SVT's foreign policy commentator Erika Bjerström.

- Last night from the EU, this is paralyzed, that the UK has not brought anything new, she says.
