The Captain and the Prime Minister by Catherine Curzon

When a devoted prime minster has a second chance at romance, he discovers that love is love on Downing Street.
Captain Tom Southwell has swapped bullets for babies and works as a manny at one of the world’s most famous addresses. Behind the doors of Downing Street, he cooks dinner, puts the children to bed and is the prime minister’s best friend.
Alex Hart is the prime minister Great Britain’s been dreaming of. He’s dedicated, caring and has a conscience. He’s also a widower with two small children. The last thing he can let himself do is fall in love with the manny who has held his family together.
When an old flame from Tom’s past gets in touch, Tom’s first instinct is to keep him at arm’s length, but hell hath no fury like a yoga teacher scorned. As Alex fights to push a life-changing bill through Parliament, the tabloid vultures are circling. With rumors swirling about the prime minister and his gorgeous manny, every shark in Westminster senses blood.
Will Alex put love ahead of duty, or will the most important man in the country be the loneliest, too?
