AS the Brexit process enters a critical period, the UK is still – officially – expected to leave the European Union on March 29.

But that could change depending on events this week.

MPs will vote on the revised Withdrawal Agreement and Political Declaration today.

The last time MPs voted on the Brexit deal in January, Theresa May suffered a humiliating 230-vote defeat.

All three Bolton MPs voted against the Prime Minister’s deal but for different reasons.

Bolton North East MP, Sir David Crausby, said the deal is the “worst of all worlds” but a no-deal Brexit would be a “catastrophe”.

Meanwhile, Bolton West MP Chris Green said he would prefer a “managed no-deal”.

If Mrs May’s plan is rejected again, MPs will vote tomorrow on whether they want a no-deal Brexit.

Should MPs reject that, there will be another vote on whether Parliament wants to delay the UK’s departure beyond the current March 29 deadline.

However, to secure an extension to Article 50, Mrs May would need the support of the 27 other EU states.

Come March 29, if there is a deal in place, although the UK will formally leave the EU, with a transition period, very little will change.

If there is a delay, the UK will still be in the European Union until the extension period expires.

But if there is a no-deal Brexit, things are a lot more uncertain.
