UK's Prince Charles called the government's intention to send people to Rwanda "appalling", according to reports. During a private chat, the heir to the throne reportedly slammed Boris Johnson's divisive migrant policy.

According to comments obtained by The Times, Charles is dissatisfied with the government's "direction of travel." He is also claimed to be enraged by the Rwanda policy's timing since he is scheduled to lead a conference in Rwanda later this month.

The Queen will be represented by the Prince of Wales at the Commonwealth Heads of Government summit in Kigali.

An anonymous source close to Charles told the newspaper: ‘He said he was more than disappointed at the policy. ‘He said he thinks the government’s whole approach is appalling. It was clear he was not impressed with the government’s direction of travel.’

It would not be the first time Charles has expressed his political views, although he has appeared a lot more impartial in recent years.

According to royal tradition, senior royals, particularly the queen, do not express their opinions on government acts, a policy that the Queen has studiously preserved.

Republicans have long claimed that Charles' involvement in politics and readiness to express his opinions in the past will put the delicate balance between hereditary monarchy and democratic democracy to the test.

Migrants who enter the country illegally fear being deported more than 4,000 kilometers to the central African country under a scheme supported by the home secretary.

The government has survived an initial legal challenge that sought to prevent the first scheduled flight from taking off on Tuesday.

Another is expected to be filed in the coming days, and the administration has previously admitted that the policy will almost certainly result in considerable litigation.

The much-contested move was widely denounced outside and within the UK, with the UN refugee agency slamming Boris Johnson's idea as a "symbolic gesture" that will be impossible to implement in fact.

Gillian Triggs, the UNHCR's associate high commissioner, told The Guardian that the arrangement would be exceedingly costly, unlawful, and discriminatory.

Moreover, the British Green New Deal Rising movement posted a video on Twitter urging the government to “drop this widely condemned policy and provide support for people seeking safety” no matter where they come from.

One of the attendees addressed British MP Priti Patel, saying, “Priti Patel, your racist policies are killing people," while another said, "We are disgusted by your treatment of refugees.”
