French presidential candidate François Fillon has suffered a new blow to his campaign, with his spokesman saying he is quitting, reports the BBC.
Thierry Solère's resignation adds to a slew of notable departures, including the campaign treasurer on Thursday.
The conservative candidate has slipped down the opinion polls amid an inquiry into political payments to his wife.
His woes have raised speculation that ex-PM Alain Juppé could return to the race if Mr Fillon were to pull out.
Mr Juppé was overwhelmingly defeated by Mr Fillon in the Republicans' primary in November, securing only 33% of the vote to Mr Fillon's 66%.
Sources close to Mr Juppé said he would be prepared to step in, but only with the unanimous support of the party and only if Mr Fillon were to go voluntarily.
A new opinion poll suggests Mr Fillon would be eliminated in the first round of presidential election voting on 23 April, and that far-right candidate Marine Le Pen would challenge independent centrist Emmanuel Macron in the two-candidate run-off on 7 May. Mr Macron would win that contest, a number of opinion polls have suggested.
Mr Fillon has so far said he has no intention of stepping down despite the continuing haemorrhage of allies.
More than 60 politicians have said they can no longer support him.
The latest, Mr Solere, said on Twitter: "I've decided to end my duties as François Fillon's spokesman."
He joins campaign treasurer Gilles Boyer, two deputy directors and Mr Fillon's foreign affairs spokesman, among others.
Mr Fillon's Paris home was raided by investigators on Thursday as part of the inquiry into the payments to his Welsh-born wife, Penelope.
