But the bloc warned it would not provide a blank cheque for the suspension of post-Brexit Irish Sea checks, with João Vale de Almeida, the EUs ambassador to the UK, stating: We remain firm on the full implementation of the protocol.
Mr Vale de Almeida also insisted the EU would continue to seek creative solutions to the problems identified by the Government.
Lord Frost is concerned the protocol is having a chilling effect on firms, with some drug companies preparing to stop supplying some medicines to Northern Ireland, and some companies in Great Britain … simply giving up and saying its too much trouble to engage with all the paperwork and bureaucracy.
He added: We have seen disorder, albeit fairly low level, at Easter, and weve seen quite a lot of protest across Northern Ireland, in various ways, amongst unionism. That just has to be factored in.
Nobody wants to see that situation get any worse and its absolutely not our wish that it should. The best situation is one of calm and we have to show that what we can do together as the UK and EU is capable of responding to those political demands.
Lord Frosts remarks came in an interview conducted on Friday as he prepared to join Boris Johnson at Chequers for talks with Angela Merkel, the outgoing German chancellor.
Downing Street said the Prime Minister reiterated the need for a permanent arrangement on the Northern Ireland Protocol that protects the Belfast (Good Friday) Agreement and safeguards Northern Irelands place in the United Kingdom.
Lord Frost said of last weeks temporary truce: The problem is, although it was good to have reached that agreement to avoid the cliff edge on June 30, it is only a tiny part of the overall problem. There is a long list of issues thrown up by the way that the protocol has been implemented. This is just one, it was the most immediate, weve resolved it for now. But theres still lots to do.
Protocol doesnt relect the balance in the Good Friday Agreement
He said the need to address the problems with the protocol was quite urgent, adding: Support for the protocol has collapsed in unionism. The latest polling shows that theres a 50/50 division in Northern Ireland. Thats just not a stable basis to proceed on. That is the problem.
He continued: It just doesnt seem unreasonable to us to say, these arrangements arent working out quite as we both thought, look at the effects and the way its playing out, we really should take another look at how its happening.
Lord Frost said that the protocol as its being operated at the moment doesnt reflect the balance that was in the Good Friday Agreement and it was intended to. If it isnt supporting the Belfast Good Friday Agreement and helping that work, then the protocol itself isnt working..
He added: Obviously not every EU leader is an expert in Northern Ireland and we wouldnt expect that. I think there are varying degrees of understanding of the issue and the status of Northern Ireland. Obviously Ireland itself has a very direct interest in this and has been encouraging of the sense that theres an issue here and we take it seriously.
I think others are perhaps a bit more focused on the process thing, that we should just implement the protocol and everything will be fine.
We dont think that quite deals with the situation as we now have it.
In a joint article in Saturdays Irish Times, Lord Frost and Brandon Lewis, the Northern Ireland Secretary, warned that the current implementation of the protocol risked damage to the Good Friday Agreement.
