Brussels: European Council President Donald Tusk on Tuesday rejected UK Prime Minister Boris Johnson's proposal to scrap the 'unviable' and 'anti-democratic' backstop plan for the Irish border.
Tusk said in a tweet, "The backstop is an insurance to avoid a hard border on the island of Ireland unless and until an alternative is found. Those against the backstop and not proposing realistic alternatives in fact support re-establishing a border. Even if they do not admit it."
According to media reports, Tusk's tweet came in response to Johnson's four-page letter to him on Monday where the British Prime Minister said the backstop risked undermining the Northern Irish peace process.
The backstop, part of the withdrawal agreement negotiated by former Prime Minister Theresa May which has been rejected by Parliament three times, is an insurance policy to prevent a hard border in Northern Ireland.
If implemented, it would see Northern Ireland stay aligned to some rules of the EU single market.
Johnson described the arrangement as "inconsistent with the sovereignty of the UK" and insisted that it could not form part of a withdrawal agreement.
If the plan was removed, Johnson claimed that a Brexit deal would be passed by parliament.
