The international relief organisation will use Barclays donation to provide emergency healthcare and shelter, food packs, and water to people in the affected areas.
Latest media reports suggest that at least 2,000 people have died as a result of the floods in the provinces of Khyber Pakhtoonkhwa, Sindh and Punjab, as well as parts of Baluchistan. The country's government officials estimate that as many as 20 million people have been affected.
Barclays is also committing a further £125,000 to support medium to long-term recovery efforts in the country, bringing total donations to £225,000.
Barclays Pakistan colleagues are also taking part in a number of volunteering activities to support short-term relief efforts.
Colleagues have partnered with two local charities, Hope and the Pakistan Red Crescent, to organise a collection drive for clothing and food items at Barclays locations across the country, including the cities of Karachi, Lahore and Islamabad. Colleagues are also raising funds to support relief efforts which will be matched by Barclays.
