Minister for Tourism, Transport and Sport Leo Varadkar has said he has had no conversations with the Taoiseach Enda Kenny about taking on the job of Health Minister.
Mr Varadkar is rumoured to be tipped for the health portfolio next year, to take over from the current minister James Reilly.
The Taoiseach has said a Cabinet reshuffle will take place in the second half of next year, after the local and European elections.
But Mr Varadkar said he's happy to stay working in his current department, and he's happy to serve the Taoiseach.
Mr Varadkar told RTE's Morning Ireland today: "I certainly haven't had any conversations with the Taoiseach about it and it is entirely his perogative."
"I'd love to stay where I am. I have a lot of objectives for next year, going into tourism again and getting the world cup bid off the ground."
"To quote Michael Collins: 'we govern to serve, not to rule,' and I'm willing to serve anywhere the Taoiseach wants me," he added.
He said he aims to increase the number of people using public transport by five million passengers, and he also wants to reduce the number of road deaths in Ireland.
