However, Mr Wilson told BBC Newsnight: “We had to do something to show our displeasure.
“None of the [amendments] have financial consequences.
“All of them were designed to send a political message to the government — ‘We’ve got an agreement with you, but you’ve got to keep your side of the bargain, otherwise we don’t feel obliged to keep ours.’”
The DUP aren’t the only ones opposing Mrs May’s Brexit agreement, as MPs across the Conservative Party have filed letters of no confidence.

To trigger a secret ballot for leadership of the Conservatives, 15 percent of the party must submit a letter to the chair of the 1922 Committee of backbench Conservatives, Sir Graham Brady.
Chief European Research Group (ERG) organisers Jacob Rees-Mogg and Steve Baker publicly declared they were sending letters of no confidence to Sir Graham Brady on Thursday.
There have been dozens of letters submitted so far, although Sir Graham has said that the 48 limit has not been reached.
However, there is still time for the number of letters to reach those needed for a vote, with Mr Baker stating: “Anyone who thinks that the moment of danger has passed has succumbed to spin. This is a process, not a moment.”

Could Theresa May want a no-confidence vote?
For those in support of the Prime Minister, a vote of no-confidence may not necessarily be a bad thing.
Should Mrs May win the vote of leadership following the no-confidence assertion, her right to office will not be able to be questioned by critics for 12 months.
This would mean when the Brexit deal is put to a vote in the coming weeks, Mrs May cannot be deposed when she would be most vulnerable should her deal be voted against.
Today the Prime Minister will meet with her new-look Cabinet following a ream of resignations last week.
In total, eight members of the Cabinet have resigned following Theresa May’s draft Brexit deal meeting last week.
These include former Brexit secretary Dominic Raab and Work and Pensions Secretary Esther McVey.
Of her resignation, Ms McVey said the Brexit deal “does not honour the result of the referendum”.
Mr Raab said he “cannot in good conscience support the terms proposed for our deal with the EU”.
The Prime Minister appointed MP for North East Cambridgeshire Stephen Barclay as Brexit Secretary in Mr Raab’s stead.
