Oliver joined in with events for Mitzvah Day across Hertsmere on Sunday.
The events ranged from knitting bonnets for premature babies in Radlett, to helping sort donations at the Watford Peace Hospice with Bushey Synagogue and clearing out the brambles at the village green on Woodstock Hill in Borehamwood.
Speaking after the events, Oliver said: ‘I was delighted joined the launch of Mitzvah Day in Parliament last month and I very much enjoyed getting involved in the great range of community projects that happened over the weekend.
‘Once again the Jewish community showed how much it gives back to Hertsmere, but it was also wonderful to see the day take place on an interfaith basis.
‘It was a pleasure to take part again this year, especially in support of the Watford Peace Hospice, of which I am a patron.’
Mitzvah Day is an annual event, led by the Jewish community where each year, groups and individuals undertake a range of volunteering projects to help those in need in their local area.
