A top Tory has hit out at the "odd" decision to exclude him from a State Banquet at Buckingham Palace in honour of Donald Trump.
Home Secretary Sajid Javid said he didn't know why he wasn't invited while lower-ranking Cabinet ministers - including Environment Michael Gove - were.
And he said "I really don't know" if it was because of his Muslim background - or his attacks on Trump for promoting far-right group Britain First.
He added: "I don't like it. It is odd. My office did ask No10 [Downing Street] and they said 'no'."
He told BBC Radio 4's Today programme: "You'd have to ask someone from No10 why they made that decision."
Mr Javid - one of 10 contenders for the Tory leadership - said he has still not received a proper explanation as to why was the only senior Cabinet minister not to be invited.
"I don't know. I have asked. I was just told that normally home secretaries aren't invited. So I don't know," he said.
Mr Javid has previously criticised Mr Trump after he tweeted his support for the right-wing Britain First group.
He responded that the president was endorsing the views of "a vile, hate-filled racist organisation that hates me and people like me".
Asked if he thought his exclusion was due to his Muslim background, Mr Javid said: "I am not saying that at all. I really don't know."
Mr Javid did meet and speak briefly with the president during the D-Day commemorations in Portsmouth on the final day of his visit.
During the course of his stay, Mr Trump renewed his long-running feud with London Mayor Sadiq Khan - who also comes from a Muslim background - branding him a "stone cold loser".
He also played the statesman at the glittering Buckingham Palace dinner, praising the Queen as he marked the 75th anniversary of the Normandy landings.
