“During their time with Alphabet, both Miles and Hannah have demonstrated the leadership qualities we look for, leading from the front with passion and vision, as well as embodying our organisational values on a daily basis.
“They now have an exciting opportunity to lead their teams working in our fast-developing ‘mobility’ space and help shape Alphabet’s customer approach in the digital age.”
