Britain's parliament has passed legislation to send some asylum seekers from the country to Rwanda. The British government hopes to begin the deportations in around July ahead of a scheduled election, despite opposition by human rights groups.

The government says a number of migrants illegally enter Britain to apply for refugee status, crossing the English Channel. It says measures to deal with the matter are a heavy financial burden.

The government has been promoting a plan for the East African country to accept the migrants in exchange for financial aid.

But Britain's Supreme Court ruled in November last year that the government's plan is unlawful as the asylum seekers could be forcefully repatriated to their country of origin.

The government inked an agreement with Rwanda that guarantees no relocated migrants will be removed from the country. It submitted a bill to parliament stating that human rights statutes will not apply to the transportation program.

The House of Lords discussed the bill on Monday and approved it, after the House of Commons.

Prime Minister Rishi Sunak said in a statement on Tuesday that "the passing of this landmark legislation is not just a step forward but a fundamental change in the global equation on migration."

He added the passing of the legislation will also make it very clear that if people enter Britain illegally, they will not be able to stay.

The issue of illegal migration has been an important matter for the Sunak administration ahead of the general election to be held by January next year. His administration promises to halt illegal migration.

Sunak said the first flight carrying asylum seekers to Rwanda will leave in 10 to 12 weeks.

The Telegraph and other local media outlets say authorities are likely to begin the detention of targeted migrants within days.

Support groups for refugees and other critics oppose the plan, saying it violates human rights.
