North Norfolk MP Norman Lamb has announced he will step down from his role as the Liberal Democrat's health spokesman.
Mr Lamb, who marked his 60th birthday on Saturday, said he would give up the role when party leader Vince Cable announces a reshuffle, which would most likely be later this month.
Mr Lamb, who is currently at the Lib Dem's Autumn Conference in Bournemouth, is also the chair of the Commons Science and Technology Select Committee.
He said: 'Taking on that role (on the select committee) was a very substantial undertaking, so when Vince Cable reshuffles after the conference as I think he probably will, I will step down as the party's health spokesman.
'I can't do both and give both proper justice.'
Mr Lamb said he would wait until the expected reshuffle so there was no gap in having someone fill the health spokesman role for the party.
