Abandoning NI protocol would be a 'grave mistake' – Blair

Former British prime minister Tony Blair: 'Once the border of the EU became the border between north and south, it was always going to be difficult.'

The neglect of the Good Friday Agreement has led to the re-emergence of tensions in the North, and only intensive efforts will be enough to solve the crisis, former British prime minister Tony Blair has warned.

Speaking alongside former taoiseach Bertie Ahern at an event in Dublin, Mr Blair urged Boris Johnson to negotiate the details on the Brexit protocol to make it work.
