Pam St Clement, who plays Pat Evans in the BBC1 soap EastEnders, is urging people to volunteer for this year's London Animal Day and help raise funds and awareness for PDSA and eight other animal charities.
The fundraising drive is now in its 71st year. Despite its name, it runs from 28 May to 9 June. Volunteers can choose to take part in house-to-house collections or shake tins at designated supermarkets.
Other charities that will benefit from the event include the Blue Cross, Cat Concern, Cats Protection, the RSPCA, the Fox Project, Friends of Animals League and Wood Green Animal Shelter.
St Clement said: "I have been associated with London Animal Day for a number of years because I greatly admire the charities involved for their work actively promoting animal welfare, ownership and protection."
Television presenters Sue Cook, Amanda Lamb and Claudia Winkleman joined John McCann, the uncle of the missing Madeleine McCann, and the Duchess of Gloucester for the rebranding of the National Missing Persons Helpline last week. The charity, which will now be known as Missing People, held the event on 24 May, the eve of International Missing Children's Day. It also relaunched its official yellow ribbon, which is currently being worn by Madeleine's family and supporters.
Lauren Laverne, the television and radio presenter, is urging visitors to this year's Glastonbury music festival to help raise money for Shelter by buying the housing charity's new festival survival kits. The kits include disposable wellies, ponchos and earplugs. For every one sold, £3 will go to Shelter's work with homeless and badly housed people.
Sally Gunnell, the Olympic gold medallist, joined more than 100 guests at the anniversary ball for Heart UK, the charity that helps families with a high risk of premature cardiovascular disease. The event raised more than £30,000 and was held to celebrate the charity's 25th anniversary at Blenheim Palace on 17 May.
Pete Doherty, frontman of indie band Baby Shambles, showed off some impressive football skills at the Samaritans' Celebrity Soccer Six tournament, despite his infamously hedonistic lifestyle. Bands including Razorlight, Towers of London and Goldie Lookin Chain also took part in the tournament at West Ham United's Upton Park stadium last week. Doherty's Baby Shambles side won the tournament.
Celebrity gardener Charlie Dimmock is the new patron of Dreamflight, a charity that organises an annual trip to Florida for seriously ill and disabled children.
Dimmock, celebrity gardener and former Ground Force presenter, became involved with the charity after a chance meeting with the founder and trustee, Pat Pearce, four years ago. Pearce says: "I was a member of the cabin crew on a flight to the US and Charlie was a passenger. I gave her one of our leaflets to read - she asked me how she could get involved."
Dimmock attended Dreamflight's next trip and acted as a volunteer carer for two children. She soon became a regular fixture on the holiday. Dimmock says: "It's a fantastic trip because you see the children become more confident and grown up."
Dinner with Dimmock was one of the lots at a recent fundraising auction for Dreamflight.
Pearce adds: "Charlie is great because she is down to earth, approachable and gets on well with the children."
