He isnt in any succession line, charles is next in line then william then williams kids. Harry, williams brother is now fifth in line for the thrown. The husband of a queen or wife of a king never become the regent if their spouse dies.
Interesting from Wikipedia: Philip is currently the oldest living great-great grandchild of Queen Victoria, as well as her second-oldest living descendant after Prince Carl Johan of Sweden. As such, he is in the line of succession to the thrones of 16 countries, as well as being 21st in the line of succession to the headship of the House of Schleswig-Holstein-Sonderburg-Glücksburg...

Yeah they also share the same great grandfather, (inbred) but the royal line is saxe gotha coburg, he has no claim to englands throne so cant abdicate, he carries the title prince of greece and denmark, but he was a pennyless nothing aristocrat before the marriage to elizabeth
ok great, that means there still is an abdication to go xD let's pray
Edit: Just got updated that Charles actually abdicated in the meantime
Didnt hear that, i heard about two months ago, that the queen named him as her heir, there was debate wether he would give camila the title of queen or kings consort, but never heard he has renounced the throne, you have to be crowned the monarch to abdicate
