Donald Trump swept all five Republican primaries held Tuesday, beating back a new alliance between Ted Cruz and John Kasich designed to deny him the 1,237 delegates he needs to win the Republican nomination on the first ballot at the convention in July.

Hillary Clinton won the biggest prize of all on the Democratic prize by taking Pennsylvania. She also took the primaries in Maryland, Delaware and Connecticut. But Bernie Sanders battled back with a win in Rhode Island and kept it close in Connecticut.
