Maidenhead MP Theresa May popped into a High Street store on Friday to recycle her Christmas cards.
The Home Secretary launched her annual campaign at Marks & Spencer as part of a campaign for the Woodland Trust.
The scheme aims to encourage people to recycle their festive greetings into woodland by dropping old cards into specially-marked recycling bins in 300 M&S stores.
Mrs May said: "This is a fantastic initiative that allows people to preserve and protect their woodland, as well as ensuring its future for generations to come."
M&S has committed to planting one tree with the Woodland Trust for every 1,000 Christmas cards brought into store.
Maidenhead store manager Andy Kendall said: "We are delighted the Home Secretary is supporting our recycling campaign.
"By donating her Christmas cards she is helping the Woodland Trust to continue its vital work in creating new woodland as well as preserving the habitat of thousands of UK species."
