A Polish politician is suing the UK government after being barred from entering the country, framing it as a free speech crackdown under Keir Starmer.

• Polish MEP Dominik Tarczyński says he was blocked from entering the UK on his diplomatic passport to give a speech, despite the invite.
• He is suing the UK and says he'll donate any payout to a UK unity movement.
• He accuses Starmer's government of acting like a communist regime by suppressing speech instead of debate.
• He contrasts the ban with the UK's acceptance of large numbers of migrants arriving by boat, who he says get housed and funded, calling the disparity absurd.

Outlook: The lawsuit could turn into a high-profile fight over free speech and immigration policy under Starmer's government.
