Communal leaders have congratulated Prime Minister Boris Johnson and his fiancée Carrie Symonds on the birth of their baby boy.
Downing Street confirmed the birth, which took place at a London hospital, in a statement on Wednesday and added that both mother and baby were doing well.
It is understood the PM, who has just recovered from coronavirus, was present throughout the birth, which took place in an NHS hospital in London.
The Board of Deputies wished Mr Johnson and Ms Symonds a "hearty mazaltov" while the Jewish Leadership Council sent their own "heartfelt congratulations" to the couple.
The Chief Rabbi tweeted "warmest congratulations" and the wish that their son "be blessed with a lifetime of joy and fulfilment".
Mark Regev, Israel’s UK ambassador, pointed out to the PM and Ms Symonds that their son was "born on Israel’s 72nd Independence Day. Mazel Tov!"
Mr Johnson only returned to work on Monday following a battle against coronavirus which saw him spend three nights in intensive care. Ms Symonds also suffered symptoms of the disease.
Communities Secretary Robert Jenrick wrote on Twitter that he was "thrilled" for the couple. "Wonderful to have a moment of unalloyed joy!", said Health minister Matt Hancock.
Meanwhile ,Michael Goldstein, President of the United Synagogue, said: “We wish mazal tov and congratulations to the TWO new dads today!
''Rabbi Yoni Golker of St Johns Wood United Synagogue, and Mr Boris Johnson of 10 Downing Street - and mazal tov and congratulations to the mums Rebbetzen Dina Golker and Ms Carrie Symons. We hope you and the babies are doing well!”
