From the House of Commons standards committee:

Mr Paisley and his family made two visits to Sri Lanka in March/April 2013 and July 2013. These visits were paid for by the Sri Lankan government. Although the precise value of the hospitality offered cannot be precisely calculated, they were of a value significantly in excess of the then registration threshold of £660. (The Daily Telegraph claimed that the cost of the visits was £100,000; Mr Paisley accepts an estimate of about £50,000.) Mr Paisley did not register either visit in the Register of Members’ Financial Interests. 

Very strong sanction:

In view of the seriousness of this matter, we recommend that Mr Paisley be suspended from the service of the House for a period of 30 sitting days starting on 4 September 2018. We also require that Mr Paisley register the benefits he received from the Sri Lankan government which will be italicised in the Register to indicate that they are a late entry.

30 sitting days from the 4 September takes us into November. This is a Brexiteer vote in the Commons lost…
