A board member of the Leave campaign resigned Monday over a series of anti-Muslim tweets, just two days before a referendum decides whether the U.K. should stay in the EU, according to British media reports.

The Guardian noted that Arabella Arkwright, who is also a businesswoman, reposted on her Twitter feed an image of a white woman surrounded by black-colored burqas along with the caption: "Britain 2050: Why didn't you stop them Granddad?"

She also reposted another message saying: "Yazidi women fleeing Isis [Daesh]" with a "Stop Islam" logo, according to the paper.

Arkwright reportedly deleted her Twitter account after she got negative reactions to her posts.

Vote Leave campaign in a statement to the paper said that Arabella's tweets did not reflect the views of the group.

"As soon as we were made aware of these tweets we asked Arabella to hand in her resignation, which she has done with immediate effect. These tweets do not reflect the views of the Vote Leave campaign," it said.

Also, Arkwright defended her position in a statement to the paper.

"I would like to make it absolutely clear that my RTs [re-tweets] and forwarding do not mean that I endorse in any way the content of them," she said.

Leave campaigners have repeatedly used xenophobic and Islamophobic content to instill fear among voters that such a move would supposedly invite millions of migrants into the bloc, especially to the U.K.

On Monday, Sayeeda Warsi, a senior Muslim politician in Britain's governing Conservative Party, also abandoned her support for Brexit.

The former Foreign Office minister had accused the Leave campaign of telling "complete lies" about Turkey's EU membership and announced she now supported a vote for Britain to remain in the European Union.
