After Nick Bourne lost his seat in May 2011, Ramsay stood for leadership of the Welsh Conservative Senedd Group against South Wales Central AM, Andrew RT Davies.

In January 2021, Andrew RT Davies was named as the new leader of the Welsh Conservatives in the Senedd and sacked Ramsay as finance spokesperson.

[2][3] On 2 January 2020 it was reported that Ramsay had been suspended from the Welsh Conservatives and his parliamentary group following what was described as a "police incident" at his home the previous evening.

Ramsay was not in the Assembly chamber for the majority of the afternoon's session, but arrived at 5.25pm to vote on a Liberal Democrat motion of no confidence in Health Minister Lesley Griffiths.

[13] Ramsay, who also celebrated his birthday that day, had intervened twice during a speech by health minister Prof Mark Drakeford AM, who at one point told him he would pursue the matters raised directly with him outside the confines of the debate.

[16] In 2020, Ramsay was accused of involvement in a further alcohol-related incident when he was seen drinking alcohol on Senedd premises during a period when this was not legal due to coronavirus public health measures.

[4] On 13 February, Ramsay confirmed that he had been reinstated to the Welsh Conservative Party Group in the Senedd and had dropped his legal challenge against the decision to suspend him.

Ramsay and his lawyers claimed the move was "unconstitutional" and warned party members could face legal costs and damages.
